Question: An electron ( mass = 9 . 1 1 x 1 0 - 3 1 kg; charge = 1 . 6 0 2

 

An electron (mass = 9.11x10-31 kg; charge = 1.602x10-19 C) is placed at the negative terminal of a parallel plate capacitor with a separation of 0.013 m. Once activated, an electric field of 2,874 N C-1 accelerates the electron towards the positive terminal. Find the magnitude of the kinetic energy of the particle when it hits the positive plate.

Give your answer in electron volts (eV) noting that 1 eV = 1.602x10-19 J.
