The uniform electric field between two parallel plates of opposite and separate loads of 40 mm has an intensity of 2 x 10*3 N/C. An electron is released from the negative plate with a zero initial vector speed. The kinetic energy of the electron, when it is returned to mid path between the plates, is: Please explain me this with explanations.
