Problem
Two large parallel metal plates are kept 3.0cm apart and maintained at a potential difference of 600V. A tiny oil drop of mass 9.0×10−16kg carries an excess charge of −1.6×10−19C.
(a) Calculate the magnitude of the uniform electric field between the plates.
(b) Determine the magnitude and direction of the electrostatic force acting on the oil drop.
(c) Hence find the magnitude and direction of the acceleration produced in the drop.
