Question

(a) Draw the equipotential surfaces due to an electric dipole.
(b) Derive an expression for the electric field due to a dipole of dipole moment ⃗pat a point on its perpendicular bisector.

Answer 1

ELECTROSTATICS

Some terms to remember :-

Electric Charge

It is the additional property of protons and electrons which gives rise to electric force between them.

Electric charge is a scalar quantity

Basic Properties of an Electric Charge :-

1. Charge is additive in nature.
2. Charge is quantized.
3. Charge is conserved.

Equipotential Surface

=> The surface having same potential at all it's point is called an equipotential surface.

Electric Dipole

=> An electric dipole is a pair of equal and opposite charges separated by a certain distance.

The first attached image is of the Equipotential Surface due to an electric dipole.

  and

The rest three images attached are of the derivation of the E. Field due to an E. Dipole on its perpendicular bisector.

Kindly have a look over it.
