1. An electrically charged macroscopic spherical oil drop of mass M=5.449x10^(-14) kg is released from rest between two electrically charged horizontal plates that produce a uniform electric field magnitude of E=1.667x10^6 N/C that is directed vertically upward. If, after release, the oil drop remains at rest, what is the the magnitude of the charge on the oil drop? 2. The attempt at a solution: qE=Mg q= Mg/E q= (5.449x10^-14)(9.8)/(1.667x10^6) q=3.203x10^-19 C ----> is this the magnitude of the charge?
