Two charges –2.0 μC and +2.0 μC are separated by 4.0 cm on the z-axis symmetrically about origin, with the positive one uppermost. Two space points of interest P1 and P2 are located 3.0 cm and 30 cm from origin atan angle 30° with respect to the z-axis. Evaluate electric potentials at P1 and P2 in two ways: (a) Using the exact formula for point charges, and (b) using the approximate dipole potential formula.
