Two large, parallel, conducting plates are 17 cm apart and have charges of equal magnitudeand opposite sign on their facing surfaces. An electrostatic forceof 4.1 x 10-15 Nacts on an electron placed anywhere between the two plates (neglectfringing).
(a) Find the electric field at the position ofthe electron.
N/C
(b) What is the potential difference between the plates?
