 Derive an expression for the torque acting on an electric dipole kept in a uniform electric field. When is this torque maximum? What will happen if the field were not uniform?
 calculate the electric field due to the electric dipole of length 2 cm having charge 4 microcoulomb at an angle of minus 60 degree for the direction of electric dipole moment 1 meter for the center to the dipole
 CALCULATE ELECTIC FEILD INTENSITY DUE TO DATIPOLE OF LENTH 10 CM HAVING CHARGE 5000MICROCOULUMB AT POINT ON AXIS OF LENTH 20 CM FROM ONE OF THE CHARGE
 An electric dipole with dipole moment 4×109cm is aligned at 30° with the direction of a uniform electric field of magnitude 5×104N/C. Calculate the magnitude of torque acting on the dipole?
 Two short electic dipoles of moment P and 8P are placed in opposite direction on a line at a distance of 15cm. The electic will be zero at point between the dipoles wose distance from the dipole of moment P is
