(8%) Problem 6: Charge q1 = 5 nC is located at the coordinate system origin, while charge q2 = 2.73 nC is located at (a, 0), where a = 0.75 m. The point P has coordinates (a, b), where b - 0.35 m. YA A third charge q3 = 18.5 nC will be placed later. (a, b) Otheexpertta.com d 4 33% Part (a) Find the electric potential Up at point P, in volts. Assume the potential is zero at infinity. A 33% Part (b) How much work W, in joules, would you have to do to bring the third charge, q3, from very far away to the point P? D A 33% Part (c) What is the total potential energy U, in joules, of the final configuration of three charges? Grade Summary U= Deductions 09% Potential 100% sin() COs() tan()
