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

detailed solution

Correct option is C

In the given condition angle between p→ and E→ is zero. Hence potential energy U=−pEcos⁡0=−pE=min.Also in uniform electric field Fnet =0.
