Calculate the dipole moment of a dipole with equal charges 2C and -2C separated by a distance of 2cm.(a) 0.02(b) 0.04(c) 0.06(d) 0.08This question was posed to me at a job interview.This interesting question is from Electric Dipole topic in section Electrostatic Fields of Electromagnetic Theory

Answer»

The correct ANSWER is (b) 0.04

To elaborate: The dipole moment of charge 2C and DISTANCE 2cm will be,

M = Q x d. THUS, M = 2 x 0.02 = 0.04 C-m.
