Problem 4: An electron is initially at rest in a uniform electric field having a strength of 1.8 × 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 0.325 m in this field? Numeric : A numeric value is expected and not an expression. AK = Part (b) Over how many kilometers would it have to be accelerated in the same electric field to increase its kinetic energy by 45 GeV? Numeric : A numeric value is expected and not an expression. d =
