Find the potential due the dipole when the angle subtended by the two

1.	Find the potential due the dipole when the angle subtended by the two charges at the point P is perpendicular.(a) 0(b) Unity(c) ∞(d) -∞I have been asked this question during an internship interview.Origin of the question is Electric Dipole topic in portion Electrostatic Fields of Electromagnetic Theory
Answer» RIGHT answer is (a) 0 The best explanation: The potential due the dipole is GIVEN by, V = m cos θ/(4πεr^2). When the ANGLE becomes perpendicular (θ = 90). The potential becomes ZERO since cos 90 will become zero.
