An electric dipole is fixed at the origin of coordinates. Its moment is directed in the positive x–direction. A positive charge is moved from the point (r, 0) to the point (–r, 0) by external agent. In this process, the work done by the agent is
- Positive and inversely proportional to r
- Positive and inversely proportional to r2.
- negative and inversely proportional to r
- Negative and inversely proportional to r2.
Answer
(D) Negative and inversely proportional to r 2 .
