Question

Derive expression for the electric potential at point p at distance r from the centre of an electric dipole making angle thi ta with its axis

Answer 1

Hey Mate..

Let P be an axial point at distance r from the centre of the dipole. Electric potential at point P is given as

⇒ V = V1 + V2

V1 and  V2 are the potential at Point P due to charges + q and - q respectively

∴ V = 1 / 4√r ₙ ( q / r - a ) + ( - q / r + a )

⇒ q / 4√r ₙ   2a / r∧ - a∧

⇒ 1 / 4√r ₙ  ( p / r∧ - a∧ )

Thank you...
