Question

A system has two charges qA = 2.5 × 10-7 C and qB = 2.5 × 10-7C located at a points A ( 0, 0, -15 cm ) and B ( 0, 0 +15 cm ) respectively what are the total charge and the electric dipole moment of the system?

Answer 1

Answer:

Explanation:

total charge = 2.5 × 10⁻⁷ + 2.5 × 10⁻⁷

                    = 5 × 10⁻¹⁴ C

distance between charges (d)= 15 +15 = 30 cm = 0.3m

electric dipole moment = q × d

=  2.5 × 10⁻⁷ × 0.3

=7.5 × 10⁻⁸ Cm along positive z - axis
