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

2q . E and minimum

B

q.E and p.E

C

Zero and minimum

D

q.E and maximum

Text Solution

Verified by Experts

The correct Answer is:
C

In uniform electric field
`F_("net") =0`
and `U_("min") = -pE ` when `theta = 0^@`
