A system has two charges `q_(A)=2.5xx10^(-7) C` and `q_(B)=-2.5xx10^(-7) C` located at points A, `(0, 0, -0.15 m)` and B, `(0, 0, +0.15 m)` respectively. What is the total charge and electric dipole moment of the system?

Explanation

Net charge `= 2.5 xx 10^(-7) - 2.5 xx 10^(-7) = 0`
Electric dipole moment,
P = (Magnitude of charge) `xx` (Sepration between charges `= 2.5 xx 10^(-7) [0.15 + 0.15] Cm = 7.5 xx 10^(-8) C m`
The direction of dipole moment is from B to A.
