Question

A charge 5C rest on the origin another charge of 3mC bring from point A via point B (2, 3, 0) cm. Find the work done to bring the charge.​

Answer 1

Given two points A and B maintained at same potential i.e, 6V. We have to calculate the work done to move a charge %C between A and B.

Since work done to move 5C between two points A and B= change in potential at two points × charge

Since change in potential between points A and B is zero, since both the points are maintained at constant potential.  

So, the work done is zero.
