A uniform electric field `E_0` is directed along positive y-driection. Find the change in electric potential energy of a positive test charge `q_0` when it is displaced in this field from `y_i=a` to `y_f=2a` along the y-axis.

Let there be a uniform electric field "E" existing along the positive X-direction.Assume electric potential to be zero at the origin.Potential at the point x=x_(0) is

A uniform electric field of 400 V//m is directed at 45^(@) to the positive X-axis, in the X-Y plane as shown in figure

A proton is placed in a uniform electric field directed along positive xx axis. In which direction will it tend to move?

A positively charged particle with specific charge sigma leaves the origin with a velocity u directed along positive x direction. The entire space has a uniform electric field (E) and magnetic field (B) directed along the positive y direction. Find the angle that the velocity of the particle makes with y direction at the instant it crosses the y axis for n^(th) time.

A positively charged particle is released from rest in an uniform electric field . The electric potential energy of the charge:
