Two parallel plates are a distance 8 cm apart from each other. Their size is large compared to the distance between them, so they can be considered as large plates. A potential difference of 156 volts is applied on them such that the left plate has the lower potential. Calculate the magnitude of the electric field at the point "p" shown in the figure. The point "p" is 3/4 of the distance from the left plate. Write your answer in N/C or V/m. D

An electron has an initial speed of 3.0 × 106 m/s. What potential difference is required to bring the electron to a stop?

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?

A solid cylindrical conductor of radius a is surrounded by a concentric cylindrical shell of inner radius b. The solid cylinder and the shell carry charges Qand-Q, respectively. Assuming that the length L of both conductors is much greater than a or b, what is the potential difference between the two conductors? ○a. V = -2k²ln(²/2) ○b. V = -2k²ln() OC. V = -k²ln(4) O d. V = -kln()
