Question

An electric dipole is placed in uniform electric field
E such that dipole moment p makes an angle 30°
with E. The force and torque acting on the dipole are
respectively
(1) 0, PE
(2) 0.0
PE
(3) O.
(4)
PE PE
2 2
2​

Answer 1

Answer:

force acting on it will be zero

Torque acting on it will be PE/2

Explanation:

• both charges on the dipole have the same force in opposite direction,they cancel each other.

and hence the net force will be zero

• Torque experience due to a dipole is given by,

T=P×E

T=PEsin30

T=PE/2

hope it helps you...thank you
