A point charge ql = -6.0 µC is at the point x= - 0.50 m, y = 1.20 m and a second point charge q2 = - 9.0 uC is at the post x = 0 m, y = 1.20 m. Calculate the magnitude and direction of the net electric force exerted by ql and q2 on the third charge, q3= - 3.0 nC located at the origin. In problem #1, find the total electric field at the origin.
