V-0.0 1. An electron is accelerated from rest to a final speed of 1.50 x 106....
An electron is initially at rest in a uniform electric field having a strength of 1.8 x 106 V/m. It is then released and accelerated by the presence of the electric field. Part (a) What is the change in the electron's kinetic energy, in kiloelectron volts, if it travels over a distance of 0.275 m in this field? Part (b) Over how many kilometers would it have to be accelerated in the same electric field to increase its kinetic energy by 57.5...
