Question

Define electric dipole moment. Derive the expression for electric field at a point (r , 0ditha) due to short dipole.​

Answer 1

Answer:

Electric dipole moment is defined as the product of either charge and the length of the electric dipole. ... Consider an electric dipole consisting of charges -q and +q seperated by a distance 2a. Let P be a point on equitorial line of the dipole at a distance 'r' from the centre of the dipole
