Consider an electric dipole lying along x-axis with its mid-point O at the origin of coordinate system as shown in figure below. Find the electric potential V at point P due to dipole. In addition to this, find electric potentials for special cases (i) When P lies on the axial line. (ii) When P lies on the equatorial line.

Two point charges are separated by a certain distance. how does the strength of the electric field produced by the first charge, at the position of the second charge, change if the second charge is doubled? a. the field does not change b. the field strength decreases by half. c. the field strength doubles d. the field strength quadruples
