Question

Two identical electric dipoles are placed along the diagonals of a square ABCD of side √2 m as shown in the figure. Obtain the magnitude and direction of the net electric field at the centre (O) of the square.

An electric dipole of length 2 cm is placed at an angle of 30° with an electric field 2 × 10⁵ N/C. If the dipole experiences a torque of 8 × 10⁻³ Nm, the magnitude of either charge of the dipole, is

The work done by an external agent in moving a unit positive test charge from one point to another along an equipotential surface in an electric field is:

The electric dipole moment p of an electric dipole is a vector quantity. Its direction is taken to be from:
