Torque on a dipole (electric field)

Description

A physical dipole consists of two equal and opposite point charges An electric dipole is a separation of positive and negative charges.The direction of an electric field is defined as the direction of the force on a positive charge. The electric field lines point away from a positive charge and toward a negative charge.When placed in an electric field , equal but opposite forces arise on each side of the dipole creating a torque. The resulting torque will tend to align the dipole with the applied field.
