Question : 65

Total: 65

A positive charge q is placed at x=0 between two infinite metal plates placed at x=−d and at x=+d respectively. The metal plates lie in the yz plane.

The charge is at rest at t=0, when a voltage +V is applied to the plate at –d and voltage −V is applied to the plate at x=+d. Assume that the quantity of the charge q is small enough that it does not perturb the field set up by the metal plates. The time that the charge q takes to reach the right plate is proportional to

d∕V
√d∕V
d∕√V
√d∕V
