Question

Two charges each 2 x 10-7 C but opposite in sign forms a system. These charges are located at

points A (0,0, -10) cm and B(0,0, +10) cm respectively. What is the total charge and electric dipole
moment of the system?

Answer 1

i) Total charge of the

system

= 2 x 10 -7 + (-2 x 10 -7)

= zero P

(ii)

P =q x 2i

P= 2 x 10-7 x 20 x 10-2

P = 4 x 10-8 cm

Direction of Dipole moment – Along negative z-axis.
