Question

Two eqaul charges q of opposite sign seperated by a distance 2a

Answer 1

Answer:

Two equal charges q of opposite sign separated by a distance 2a constitute an electric dipole of dipole moment p . if p is a point at a distance r from the centre of the dipole and the line joining the centre of the dipole to this point makes an angle θ with the axis of the dipole, then the potential at p is given by.
