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
Text Solution
Verified by ExpertsThe correct answer is:
C
The total force on dipole is zero because 
is applied on each charge but in opposite direction. The potential energy is 
, which is minimum when 
and 
are parallel.
