Question: 48 p the drawing shows a positive point charge qi...

Question details

*48. p The drawing shows a positive point charge +qi, a second point 55, ss charge q2 that may be positive or negative, and a spot labeled P, all on an edg the same straight line. The distance d between the two charges is the surface same as the distance between q1 and the spot P. With q2 present, the mutual magnitude of the net electric field at P is twice what it is when qi is present has an alone. Given that qi +0.50 μC determine q2 when it is (a) positive surface The e drawin magnit (a) sur and (b) negative. +91 42
