The electric dipole of dipole moment p is placed in a uniform electric field E. Then, the
A
torque experienced by the dipole is 
B
torque is zero, if p is perpendicular to E.
C
torque is maximum, if p is perpendicular to E.
D
potential energy is maximum, if p is parallel to E.
Text Solution
Verified by ExpertsThe correct answer is:
C
Torque on dipole, 
. So, torque is maximum if p is perpendicular to E. Potential energy 
Hence, when 
, i.e. 
is anti-parallel to E, then potential energy will be maximum.
