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
- A2q.E and minimum
- Bq.E and p.E
- Czero and minimum
- Dq.E and maximum
View written solutionFree
Correct answer: C
When the dipole is in the direction of field then net force is qE + (–qE) = 0

and its potential energy is minimum = – P.E. = –qaE
