Find potential at point A and B due to the small charge -system fixed near origin. (distance between the charges is negligible).

Answer»

SOLUTION :Dipole MOMENT of the system is
`vec(P) = (qa) + (qa) hat(j)`
Potential at POINT A due to the dipole
`V_(A) = K((vec(P).vec(r )))/(r^(B)) = (K[(qa) hat(i) +(qa)hat(j)].(4 hat(i) + 3HAT(i)))/(5^(3)) = (k(qa))/(125)(7)`
`rArr V_(B) = (K[(qa) hat(i) +(qa)hat(j)](3hat(i) - 4hat(j)))/(5^(3)) = (k(qa))/(125)`
