Question

A charge of 25 C is moved from infinity to points A and B, and the work done to do so is 10 J and 11 J, respectively. Calculate the potential difference between points A and B.

  1. - 0.04 V
  2. 12.5 V
  3. 0.04 V
  4. - 0.82 V

hintHint:

work done=charge*potential difference.

The correct answer is: - 0.04 V


    Work done to move 1C charge from Point A to B=10-11=-1 J
    work done=charge*potential difference.
    potential difference=work done /charge
    =-1/25=-0.04V
