Charge q1=12 nC is located at the coordinate system origin, while charge q2=3.55 nC is located at (a,O), where a=0.85 m. The point P has coordinates (a,b), where b=0.75 m. A third charge q3=16 nC will be placed later. A) find the electrical potential Vp, at point P, in volts. Assume the potential is zero at infinity. B) how much work W and joules, would you have to do to bring the charge, q3, from very far away to the point P? C) what is the total potential energy U, and joules, of the final configuration of three charges?
