उत्तर
Depicting the orientation of the dipole in
(i) stable equilibrium in a uniform electric field
Net force is zero in this case as qE - qE = 0
Net torque = pEsinθ as θ = 0°
(ii) unstable equilibrium in a uniform electric field.
Net force is negative in this case as - qE - qE = -2qE
Net torque = pEsinθ as θ = 180°
