Question

in electrostatic potential - potential due to a dipole in equitorial position why we have to take direction (potential is a scaler quantity)​

Answer 1

Direction of electric field on the equitorial line of the dipole. By Coulumb's Law, the direction of the electric field at P due to charge +q will be away from itself whereas due to point charge +q, it will be towards itself (-q), in the line joining the two changes.
