The drawing shows a positive point charge +q1, a second point charge q2 that may be positive or negative, and a spot labeled p, all on the same straight line. the distance d between the two charges is the same as the distance between q1 and the spot p. with q2 present, the magnitude of the net electric field at p is twice what it is when q1 is present alone. given that q1 = +0.20 μc, determine the magnitude |q2| when q2 is
