An electric dipole has the magnitude of ...

An electric dipole has the magnitude of its charge as q and its dipole moment is p. It is placed in a uniform electric field E. If its dipole moment is along the direction of the field, the force on it and its potential energy are respectively

A

2qE and minimum.

B

qЕ and pE.

C

zero and minimum.

D

qE and maximum.

Text Solution

Verified by Experts

The correct Answer is:
C
When `vecp` is along the direction of electric field `vecE`, the net force acting on the dipole is zero and its potential energy is minimum having a value - pE.
