Proton Definition and 836 Threads

I have no idea what formulas I'm supposed to use here, or possibly how to use them... any help would be great... Protons are projected with an initial speed vi = 9.73 103 m/s into a region where a uniform electric field E = (-720 j) N/C is present, as shown in Figure P23.49. The protons are...

Is it possible that the magnetic field of the proton is strong enough to force the electron to stay away from the proton? Do neutrons exert more magnetic force than protons?

A neutron at rest in the laboratory spontaneously decays into a proton, an electron, and a small essentially massless particle called a neutrino. Calculate the kinetic energy of the proton and the electron in each of the following cases: a) the neutrino has no kinetic energy b) the neutrino...

some theorist predicts proton can decay, since the decay of proton does not violate any fundemantal conservation law. My question is, could neutrino decay? How come I have never heard of anyone say neutrino could decay?

Hello, and thank you for your existence. I have been reading posts since the beginning of last semester. I must take physics as a degree requirement, and I have in the past had a lot of trouble with understanding the concepts of physics, or really I have more trouble trying to understand how...

wat is the mass of a proton?

A proton traveling at v= 1.0*10^5 m/s enters the gap btwn the plates of a 2.0-cm-wide parallel-plate capacitor. The surface charge densities on the plates are +-1.0*10^6 C/m2. How far has the proton been deflected sideways when it reaches the far edge of the capacitor? I figured that the...

Hi, The other day I was reading and the article I was reading mentioned positive current AKA proton current. ( Can't remember if it was a periodical or Quantum mechanics book...) Would this be the same as normal electron current? How would you create a potential diffrence if not the same...

We all know that magnetic fields come from moving charge or electron spin. However if it were possible to have protons as a moving charge in a wire does that cause a B field? At first I thought that it obviously should but then I thought about how accelerating electrons emit EM waves...

what is the end result when you break a proton down? I know that the charge is called a positron but what is the other half of the proton called?

In all situations (that I can think of) of particles relaxing from an excited state to their ground state, the direction of the resultant photons is isotropic. In magnetic resonance imaging (MRI) the excited protons are all in the -Z direction (+ some thermal motion). Will this have any bearing...

Sorry if the question is too stupid, but, How about receiving an impact of a proton (or electron, with less mass) fired from a particle accelerator at just below c? What will be the consecuencies in my body?

Little task : The great unification theory says that there is a very little probability that the proton will disintegrate for meson pi0 and positron (e+) . In one of the experiments ,checking this theory, there were 3300 tons of water obserwed using very sensible gear , the gear can...

I recently saw posts indicating that the SM does not have baryon and lepton number as exact symmetries, and in fact allows protons to decay, but with much smaller probabilities than GUT's. What is the mechanism by which such decays can occur (is it non-perturbative?), and what order of magnitude...

A proton of mass m undergoes a head-on elastic collision with a stationary carbon nucleus of mass 12×m. The initial velocity of the proton is 790 m/s in the positive x direction. Find the velocity of the center of mass of the system. I am really confused as to how to find the 'velocity of...

Hi, can someone remind me why should we expect a proton to decay? The last I heard, people put detectors around stored protons and expected some of them to undergo spontaneous decay, but nothing was ever detected, suggesting that the half-life of protons was longer than measurable time scales...

isn't a neutron more massive thatn a proton?

Do protons also exist as "proton waves" similar to the "electron waves"? Akira Tonomura has written a book called "The Quantum World Unveiled by Electron Waves" published in 1998 by World Scientific. In his book, he explains that in 1955 G. Moellenstedt and H. Dueker of Tuebingen University in...

When a beam of electrons (near relativistic or non-rel.) intersects with a beam of protons or a "fixed" proton target, what percentage of the electrons tunnel through the proton(s) or is there an absence of electrons on the exact opposite side (the backside) of the proton? This question is a...

I hear about a process called DVCS ("Deeply Virtual Compton Scattering") which should allow access to new distributions of parton called "generalized" distributions. Does someone know what's new about those "GPD" ? DVCS at JLab Hall-A

what is the difference between electron volts and proton volts?

is proton volt = electron volt? if yes then why? even if proton is 1840 times massive then electron and eV Is work done in carrying an electron from one potentail difference to another when potentail differnece is 1 V.

Why is the half-life of a proton, what it is? Can any branch of Mathematics or Physics explain it or predict it. I have asked myself these very same questions many times before. We are closer to finding, a tachyon than a proton-decay. Not that I am complaining since proton decay...

Hi I've been reading websites about particle physics recently, and in some places they say the proton is stable and others they say it is unstable, with a half life of 10 to the power of 32 years. I know it is the most stable baryon. The only possible decay I've read about is a proton...

Can some one help me out here, I have tried using several different methods but I still don't know what I am doing wrong. The question is: A proton in a high energy accelerator moves w/a speed of 0.5c, use the work-energy theorem to find the work required to increase its speed to 0.7c...

A proton of mass m undergoes a head-on elastic collision with a stationary carbon nucleus of mass 12m. The velocity of the proton is 395 m/s in the positive x direction. The velocity of the center of mass of the system is 30.38 m/s. What is the velocity of the proton after the collision?

Proton in Magnetic field -- am I correct? One of my Physics ISU questions is as follows: - A proton moves in a circular path perpendicular to a 1.10 T magnetic field. The radius of the path is 4.5 cm. calculate energy of the proton in eV Well i had hard time doing it but here we go: my...

Hello. I remember a problem I had with drawing a splitting tree for nitrotoluene. The coupling constants varied, you know, para, meta, ortho, they were all different. My teacher told us to assume certain values for each. What I don't understand is how a proton in nitrotoluene (or even toluene...

Yeah, I'm having difficulties with this one question... A stationary proton holds an electron in suspension underneath it against the force of gravity. How far below the proton would the electron be suspended? I understand that Fe = Fg so i would have __ = mg... but i don't know what...

Dear reader, What is the excat charge on a electron and proton? What is the net energy in a electron? I strongly feel that the charge on a electron is not a constant. -Benzun all for God.

What do you make of this, now that the theory has some math... Just seeing what you think. Paden Roder http://www.geocities.com/natureoflight/natureoflight

Wow. Clean slate! I like the format! And I've got a question. In elementary physics, it is said that the neutron can "sorta" be thought of as a proton plus an electron together. The mass of the neutron is slightly higher than a proton, by approximately the mass of an electron; in beta...

Hello, What happens to the kinetic energy of a speedy proton when its relativistic masss doubles? a) it doubles b) it more than doubles c) it less than doubles d) it must increase but impossible to say by how much Now, what kind of question is this? Or should I ask what klind of...

A proton moves .1m along hte direction of an electric field of magnitude 3V/m. what iss the change in kinetic energy of the proton? I have KE = qE/d...1.6x10^-27 * 3V/m /(.1^2)= 4.8x 10^-25 but got it wrong on the test. What did i do wrong? Dx

Hello, I need help deriving a formula to solve for this please. A proton has a speed of 3 x 10^6 m/s in a direction perpendicular to a uniform magnetic field and the proton moves in a circle radius .2 m. what is the magnitude of the magnetic field? If someone can show me the all formulas...

A proton moves .1 m along the direction of an electric field of magnitude 3 V/m. What is the change in KE of the proton? Is this the corrrect formula? KE = Q_pV_accel Through substition i came up with an swer of 3.2x10^-20J but i don't think its correct? Can you help me solve for this...
