48. Go The drawing shows a positive point charge +91, 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 q, and the spot P. With qz present, the magnitude of the net electric field at P is twice what it is when q, is present alone. Given that qı = +0.50 4C, determine q2 when it is (a) positive and (b) negative. 92 +91 ?
