The diagram below show region of equipotentials.

A positive charge is moved from A to B in each diagram .

A

In all the four cases the work done is the same

B

Minimum work is required to move q in figure (a)

C

Maximum work is required to move q in figure (b)

D

Maximum work is required to move q in figure (c )

Text Solution

Verified by Experts

The correct Answer is:
B
`W=q Delta V` For all cases potential difference remains same hence work done is same for all cases.
