Question

prove that electric potential is zero on the equatorial position of an electric dipole​

Answer 1

Answer:

Now there is a point "P" on the bisector of the dipole. The point "P" is placed at distance r from the midpoint "O". Potential (P) = V1 + V2 = 0. After calculations, the net potential will become zero at the bisector position due to the length of the dipole.
