Same equipotential lines distributed in ...

Same equipotential lines distributed in space are shown below. A charged object moves from A to B

A

Work done is same in fig (I), (II) nad (III)

B

Work done is greatest in fig (I)

C

Work done is least in fig (II)

D

Work done in fig (III) is greater then fig (II) but equal to that in fig (I)

Text Solution

Verified by Experts

The correct Answer is:
A
Work done is given by `W_(12)= q(V_(2)-V_(1))`
Hence, the initial and final potential is same in all the figure.
