In a parallel plates, E=12,000 N/. The distance between the plates is 40 mm. A device shoots out an electron from plate A, toward plate B, with an initial speed of vo = 2.0 x 10 m/s. a) What is the electric force on the electron? b) What is the potential difference between the two plates? A B E = 12,000 N/C Vo 40 mm
