Question

potential of a point x is 30 and point Y is -20 what will be work done for bring 10 c charge from x to y or vice versa​

Answer 1

Electric potential at a point X due to the point charge of 1 μC located at 10 cm from it is

.

The work done in bringing a charge of 2 × 10-9 C from infinity to the point X is given by:

W = qo V

W = 2 × 10-9 C × 9 × 104 V = 18 × 10 -5 J = 1.8 × 10-4 J
