A system has two charges `q_(A)= +2.5xx10^(-7)C and q_(B)= -2.5xx10^(-7)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 of the system?

Explanation

Total charge`=2.5xx10^(-7)-2.5xx10^(-7)=0`
Electric diople moment,
p=Mangitude of either charge `xx` separation between charges
`=2.5xx10^(-7)[0.15+0.15]C m=7.5xx10^(-8) Cm`. The direction of dipole moment is front B to A.
