A 6 g ball with a charge of 4 μC hangs by a thread between two oppositely charged parallel plates as shown below. The distance between the ball & the edges of the plates is much greater than the distance between the plates. Each plate has the same constant uniform charge density. A + 30° Determine the voltage between the plates. -61.9806 V X 67.8963916567 V Determine the polarity of each plate. You will not receive credit until you have correctly selected the polarities of both plates. left plate neutral right plate impossible to determine 8 mm ×

Two large parallel plates are separated by a 0.015-m gap. The plates are connected to the terminals of a 12-V battery, which remains connected. a) What is the strength of the electric field in the region between the plates? b) What happens to the strength of the electric field if the gap between the plates is reduced to 0.010 m? Justify your answer. c) Does charge flow through the battery as the separation between the plates is being reduced? Explain your answer.

A capacitor is composed of two metal plates. The two plates have the dimensions L = 0.11 m and W = 0.56 m. The plates have a distance between them of d = 0.1 m, and are parallel to each other.  Part (a)  The plates are connected to a battery and charged such that the first plate has a charge of q. Write an expression for the magnitude of the electric field, |E|, halfway between the plates.  Part (b)  Input an expression for the magnitude of the electric field, |E2|, just in front of plate two.  Part (c)  If plate two has a total charge of q = -1 mC, what is its charge density, σ, in C/m2?

The voltage is constant inside the circular electrodes. What does that mean for the electric field inside the electrode. (the electric field inside a conductor is zero!). Draw arrows from the dots within this electric field to show what would happen?
