An Electric Dipole Consists of a Particle with a Charge

Multiple Choice

An electric dipole consists of a particle with a charge of +6 * 10^-6 C at the origin and a particle with a charge of -6 * 10^-6 C on the x axis at x = 3 * 10^-3 m.Its dipole moment is:

A) 1.8 * 10^-8 C.m, in the positive x direction
B) 1.8 * 10^-8 C.m, in the negative x direction
C) 0 C.m, because the net charge is 0
D) 1.8 * 10^-8 C.m, in the positive y direction
E) 1.8 * 10^-8 C.m, in the negative y direction
