Find the electric potential at point A and B due to two small sphere X and Y 1.0m apart in air and carrying charges of +2.0 x 10^-8 C -2.0 x 10^ -8 C respectively. Assume the permittivity of air = e0 and 1/4 pie0 = 9 x 10^9Nm^2C^-2..fig attached

|dw:1347280576932:dw|
on B =0, for A plug in r1=1m,q1=20nC ;q2=-20nC,r2=2m
potencial is scalar
