Question

Derive an expression for the electric field at a point on the equatorial plane of an electric dipole consisting of charges q and −q separated by a distance 2a.

The distance of a far off point on the equatorial plane of an electric dipole is halved. How will the electric field be affected for the dipole ?

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
