Derive the expression for torque on an electric dipole placed in a uniformelectric field. |
Answer» Solution :Consider an electric dipole of dipole moment `p= q xx 2A` in a uniform electric field. where `q to ` MAGNITUDE of EITHER charge and `2a to ` distance between the charges. LET `. theta’` be the angle made by the axis of the dipole with the direction of E and `F=qE `by the magnitude of the force experienced by either charge. The magnitude of the torque is given by Torque = Magnitude of either force `xx` PERPENDICULAR distance between the forces.
