An electric dipole is an arrangement of two equal charges of equal magnitude but opposite nature, separated by some fixed distance.
Now consider a dipole enclosed inside a closed surface S. The flux through the surface S is zero.
An electric dipole consists of two opposite charges of magnitude 1μC separated by a distance of 2cm. The dipole is placed in an electric field 10−5Vm−1. The maximum torque that the field exerts on the dipole is:
