Two point-charges of +1uC and -luc are kept at a distance of 2 cm. They form an electric dipole.
This dipole is situated in a uniform electric field of
1 x 105N-C-1, with dipole moment vector p making
an angle of 30° with the field. Calculate (i) the
magnitude of electric dipole moment and (ii) the
torque acting on the dipole. (iii) When would be the
torque maximum? How much?
