A system has two charges `qA = 2.5 xx 10^(–7) C and qB = –2.5 xx 10^(–7)C` located at points A: (0, 0, –15 cm) and B: (0,0, +15 cm), respectively. What are the total charge and electric dipole moment of the system?

Text Solution

Verified by Experts

Net charge `=2.5xx10^(-7) -2.5xx10^(-7)=0`
Electric dipole moment, `P = ("Magnitude of charge")xx("Separation between charges")`
`=2.5xx10^(-7) [0.15+0.15]C m =7.5xx10^(-8) Cm`
the direction of dipole moment is from B to A.
