1. The problem statement, all variables and given/known data A small ball with a mass of 35 g and a charge of -0.1 µC is suspended from the ceiling by a string. The ball hangs at a distance of 5.0 cm above an insulating floor. If a second small ball with a mass of 85 g and a charge of 0.2 µC is rolled directly beneath the first ball, will the second ball leave the floor? ans: 0.415 N 3. The attempt at a solution T of the ball T = mg = 0.035kg * 9.8 = 0.343 N F of two balls F = k * q1* q2 / (l)^2 = 0.021576 N i am not sure what to do any hints?
