Coloumbs Laws and electric fields

AI Thread Summary
To determine the acceleration of a proton in an electric field of 500 N/C, use the formula F = q * E, where q is the charge of the proton (+e). The force acting on the proton can be calculated, and then acceleration can be found using F = m * a. The acceleration is significantly greater than that due to gravity, which can be calculated for comparison. Understanding the relationship between force, charge, and electric fields is crucial for solving this problem.

Determine the acceleration of a proton (q = +e, m = 1.67 E -27)
in an electric field of intensity 500 N/C. How many times is this acceleration greater then that due of gravity

I'm not so understanding on todays lessons
teh 2 formulas I can recall are f = q*e
and e = f/q
but i don't see that helping here, can someone help me start off
thanks guys.
 
Physics news on Phys.org
HINT: Force = mass x acceleration
 
yup i knew of that
i got mass, I am looking for acceleration
but what's force
f = q * e right
i got e just don't know what q is (what they mean by q = +e)
 
oh roger that
thanks

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
