Question

the electric potential in equatorial position of an electric dipole is ​

Answer 1

The net potential will become zero at the bisector position due to the length of the dipole.

Explanation:

• Consider there are two charges positive and negative. + q and - q  
• Both are placed at a distance 2 l from the center position.
• 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.
