An electron (mass m = 9.11x10^-31 kg) is released in the uniform field (E = 2.0x10^4 N/C) between two parallel charged plates. The separation of the plates is 1.5 cm. The electron is accelerated from rest near the negative plate. If the gravitational force can be ignored, determine (a) the direction of the electric force acting on the electron; (b) the magnitude of the electric force acting on the electron; (c) the velocity of the electron after 2.0 ns; (d)...
