1. The problem statement, all variables and given/known data A point charge of -0.35nC is fixed at the origin. Where must an electron be placed in order for the electric force acting on it to be exactly at it's weight. 2. Relevant equations Fe=Kqq/d^2 3. The attempt at a solution All I know is that n is an exponential value of -9 so -0.35*10^-9C that's all I know plz help.
