The diagrams below show regions of equipotential.

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

A positive charge is moved from AA to BB in each diagram.

Options

  1. AMaximum work is required to move qq in figure (c).
  2. BIn all the four cases the work done is the same.
  3. CMinimum work is required to move qq in figure (a).
  4. DMaximum work is required to move qq in figure (b).

Correct answer

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

Step-by-step solution

Work done, W=q\DeltaVW = q\DeltaV.

\DeltaV\DeltaV is same in all the cases so work is done will be same in all the cases.
