1.

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 respectivelyA. q. E and p. EB. zero and minimumC. q. E and maximumD. 2q. E and minimum

Answer» Correct Answer - B
`F=p"dE"/"dr"=0` (`because` E= constant )
`u=-vecp.vecE`=-PE (minimum )
