An electric dipole of length 2 cm is placed with its axis making an angle `30^(@)` to a uniform electric field of `10^(5)` N/C if i. experiences a torque of `10sqrt(3)` N-m, calculate (i) the magnitude of charge on the dipole and (ii) potential energy of dipole.

Answer

(i) `sqrt(3)xx10^(-2)C` (ii) `-30` J
