Q.
The diagrams below show regions of equipotentials.

A positive charge is moved from A to B in each diagram. [2017]

1 In all the four cases the work done is the same.

2 Minimum work is required to move q in figure (I).

3 Maximum work is required to move q in figure (II).

4 Maximum work is required to move q in figure (III).

Ans.
(1)

Work done is given as $W = q Δ V$

In all the four cases the potential difference from A to B is same.

$∴$ In all the four cases the work done is same.
