  1. A  In all the four cases the work done is the same.
  2. B  Minimum work is required to move \(q\) in figure \((I).\)
  3. C Maximum work is required to move \(q\) in figure \((II).\)
  4. D Maximum work is required to move \(q\) in figure \((III).\)
Verified Solution

Answer & Solution

Correct Answer

(A)  In all the four cases the work done is the same.

Step-by-step Solution

Detailed explanation

Work done is given as \(W=q \Delta V\) In all the four cases the potential difference from \(A\) to \(B\) is same.
