Indicate the direction of the electric field between the plates of the parallel plate capacitor shown in the drawing if the magnetic field is decreasing in time. Give your reasoning. Please help me.. how can i do this?

Three very large square planes of charge are arranged as shown (on edge) in Fig. 21-70. From left to right, the planes have charge densities per unit area of -0.50 µC/m2, +0.20 µC/m2, and -0.30 µC/m2. Find the total electric field (direction and magnitude) at the points A, B, C, and D. Assume...

Experiment: investigating E field btw parallel plates using a charged foil strip In the expt., E field was set up between 2 parallel plates and a positively charged foil was placed at the middle in between. The EHT supply was adjusted so that the foil deflected 45deg for different chosen plates...

What is the best way to etch copper with house hold materials? It is for making print plates.

Which of the statements below are true for two oppositely charged, isolated parallel plates? (C is the capacitance, U is the stored energy, +Q and -Q are the charges on the plates.) Note: isolated plates can not lose their charge. (Enter ALL correct statements, e.g., BCD) A) When the...

1. parallel plate with capacitor of 20uF, plate is 0.5mm apart. Find 1. Area of each plate 2. potential difference if there's a change of magnitude of 30uC on each plate. 3. stored energy 4. electric field between the two plates 5. charge density on the plate. |_| |_|...

How is potential difference found between two plates in a B-field? Any help is greatly appreciated.

Small question: The capacitance of parrallel plates decreases as you increase the distance between them, why? I know the voltage increases, because the electric field is constant, but how does this stop more charge from entering the plate? I mean our voltage relative to some far-off charge is...

Alright, here's the problem. You're told that there are two square metal plates with side length L and a distance d away from each other. One has charge +Q, the other -Q. Then they ask for the magnitude for the charge between the plates, not close to the edge. Here's what I have so far: The...

We were told that the electric field between two oppositely charged parallel plates was uniform in any region between them: like +++++++ ------------- but the teacher didn't really explain why: it makes sense that they'd always be in the same direction, but how would you prove that...

5. Two parallel plates labeled W and X are separated by 5.2 cm. The electric potential between the plates is 150V. An electron starts from rest at time tW and reaches plate X at time tX. The electron continues through the opening and reaches point P at time tp (remember e = - 1.6 X 10^-19 C and...

If two capacitor plates at a moderate voltage (200-300V) and low capacitance are kept very close to each other would there exist a tunneling current between them. If the tunneling current will exist, then it will gradually reduce the energy of the capacitor. Where will the used capacitor...

I was wondering if someone could help me out here. It seems that no matter how many textbooks i consult, each one has a slightly different version of the plate tectonics map. There seems to be some amount of confusion about the boundary between the Eurasian and American plates, the plates at the...

Help! Parallel Plates Velocity of Electron New to the forums and am hoping to find some major help... I need some help understanding parallel plates and how to calculate the velocity of an electron going through them. What formula's would I use? Any help would be appreciated...please help...

Another question for Gauss' Law; A very large, thin, flat plate of Aluminium of area A has a total charge Q uniformly distributed over its surfaces. If the same charge is spread uniformly over the upper surface of an otherwise identical glass plate, compare the lectric fields just above the...

A parallel plate capacitor has charge Q and plates of area A. What force acts on one plate to attract it toward the other plate? It's F = Q^2 / (2*8.854e-12*A) ... something to do with the electric field divided in 2? Wondering why there's a 2 in the denominator... thanks :)

Hi I am trying to solve this problem. I would like to be able to solve for the capacitance between two parralel plates of different areas. First I tried thinking of them as concentric cylindrical shells but twisting them to do this is not the same thing I realized because the distance...

Excerpt from: Beicher and Serway, "Physics for Scientists and Engineers with Modern Physics, 5th edition" Chapter 24, problem 58, part c: Two infinite, non conducting sheets of charge are parallel to each other, as show in the figure. The sheet on the left has a uniform...

Howdie all, I'm soo glad I found this forum, people are genuinely working together instead of ignoring their fellow physics brethren =) A pair of square parallel conducting plates, having sides of length .05 meter, are .01 meter apart and are connected to a 200 volt power supply. An electron...

Here's my problem: A parallel-plate air capacitor has a capacitance of 730 picoFarads. The charge on each plate is 2.95 microCoulombs. a) What is the potential difference between the plates? I used the equation V=Q/C to get 2.4746E-4 V, but this is incorrect. b)If the charge is kept...

Can someone give me three real life applications of the Millikan Experiment or parallel plates? Also if possible can you give me a little description of how it works. Also, we are not allowed to use a tv,computer monitor or a printer.

Two parallel thin metallic plates with a gap between them are used as a heat insulator. How does the heat flow rate through this device depend on the temperatures on its two sides in the following two cases? Case 1: The gap is filled with air. Case 2: There is a vacuum in the gap.
