Question

(a) Derve the expression for electric fiell at a point on the equatorial line of an electric
dipole (b) Depict the orientation of the dipole in (0) stable. (10) unstable equilibrium in a
uniform clectric field​

Answer 1

The stable position of the dipole is parallel to the direction of the electric field index for dipole at unstable position is perpendicular to the direction of the electric field .
