An electron (mass = 9.1 x 10^-31 kg and charge = -1.60 x 10^-19 C) is initially at rest just to the right of the leftmost plate. The separation between the two plates is 4.00 cm. A uniform electric field of 5000 N/C directed to the left is suddenly applied between the two plates. A) What is the force on the electron? B) What kinetic energy will the electron have when it strikes the other plate?
The solution includes calculations for the force of an electric field on an electron in between to plates and the kinetic force of an electron when it strikes one of the plates.
