l. (15 points} A point charge with a weight of L5 N and a 4?. charge 4:]: = +24 mt? is placed 8\"? cm above a uniformly charged 30 cm sheet with charge density +0 as shown. {a} The charge levitates in place. so the electric force is equal to the weight. Find a on the sheet charge in this case. (5 pts) (b) A second point charge 3 = +2.2 NC is placed 80 cm directly to the le of the rst point charge as shown. Find the magnitude of the net electric force on q}. (7 pts) {c} What angle does the net eld make. up from horizontal? (3 pts}
