1. The problem statement, all variables and given/known data A tiny ball (mass = 0.014 kg) carries a charge of -17 C. What is the electric field magnitude that would cause the ball to float above the ground? 2. Relevant equations what equation should I use? I am not sure how to even start this problem. 3. The attempt at a solution Would using E = q/ ((E0 * A) be a good start?
