Question

The diagrams below show regions 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)

Work done w=q Δ V Δ V is same in all the cases so work is done will be same in all the cases.

Q. The diagrams below show regions of equipotentials. A positive charge is moved from $A$ to $B$ in each diagram.

In all the four cases the work done is the same

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

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

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

Work done $w = q Δ V$
$Δ V$ is same in all the cases so work is done will be same in all the cases.
