Assignment:
3 point charges Q1, Q2, Q3 are located in the xy plane at points (-10,0), (10,0) and (-5,12) respectively.
The charges are given values Q1 = 5 uC, Q2 = -10 uC, Q3 = 8 uC. You may assume that the distance between charges is in units of cm
(A) Calculate the Electric Potential at the origin, point (0,0)
(B) Determine the work done in moving a charge of 3 uC to the origin from infinity under this potential
