Two large, parallel, conducting plates are 16 cm apart and have charges of equal magnitude and opposite sign on their facing surfaces. An electrostatic force of 5.3×10−15 N acts on an electron placed anywhere between the two plates. (Neglect fringing.) (a) Find the magnitude of the electric field at the position of the electron. (b) What is the magnitude of the potential difference in volts between the plates? (a) Number Units (b) Number Units
