A system has two charges and are located at a given distance. What will be the total charge and electric dipole moment vector of the system?

A system has two charges qA=2.5×10<sup>-7</sup> C and qB=-2.5×10<sup>-7</sup> C located at point A(0,0,-15) cm and B(0,0,15) cm respectively. What are the total charge and electric dipole moment vector of the system?

Solution:

At A, the amount of charge, qA = 2.5×10<sup>-7</sup> C

At B, the amount of charge, qB = -2.5×10<sup>-7</sup> C

Total charge of the system, q = qA+qB = 2.5×10<sup>-7</sup> C = 0

Distance between two charges at points A and B, d = 15+15 = 30 cm = 0.3 m

Electric dipole moment of the system is, p = qA x d = 7.5×10<sup>-8</sup> cm 

The electric dipole moment is along the z-axis
