Question

The potential at a point is 20 V. The work done in bringing a charge of 0.5 C from infinity to this point will be?

Answer 1

SOLUTION :

        Work done according to given data will be 10 J.

Electric potential at a point is defined as the change in potential energy or work done to bring charge from infinity to a particular point.

For this, electric potential at infinity is assumed to be zero.

V = W/Q

Given values are -

V = 20 V

Q = 0.5 C

W = V*Q

W = 20*0.5

W = 10 J

Therefore, work done to bring a charge of 0.5 C from point to infinity is 10 J.

Answer 2

Answer:

10J

Explanation:

V=20V

Q=0.5C

V=W/Q

W=VQ

W=20×0.5=10J
