Question

a dipole is placed in an uniform electric field.At what angle between the dipole moment and electric field is the dipole is
I) stable equilibrium
ii) unstable equilibrium​

Answer 1

Answer:

The potential energy of electric dipole is,

U=−

P

.

E

=−PEcosθ

where E= uniform electric field

P=Electric dipole

θ= angle between field and dipole

The potential energy is minimum when θ=0

U=−PE
