Problem

An oil droplet of mass 2.0×10−6 kg2.0\times10^{-6}\,\text{kg} carries a charge of −1.2×10−8 C-1.2\times10^{-8}\,\text{C}. The droplet is to be held stationary midway between two large horizontal plates separated by 0.80 cm0.80\,\text{cm}. Assuming the upper plate is positive, what potential difference between the plates is required? (a) 1.3×102 V1.3\times10^{2}\,\text{V} (b) 1.3 V1.3\,\text{V} (c) 13 V13\,\text{V} (d) 1.6×103 V1.6\times10^{3}\,\text{V}
