उत्तर
A dipole placed in a uniform electric filed is in
Stable equilibrium when the electric field is directed along the direction of the dipole i.e., when `vecE` is parallel to`vecp`.
Unstable equilibrium when the electric filed is directed at an angle of 180 degrees with the direction of the dipole, i.e., when `vecE` is anti-parallel to`vecp`.
