An electron of mass 9.11x10^-31 kg has an initial speed of 3.00x10^5 m/s. It travels in a straight line, and its speed increases to 7.00x10^5 m/s in a distance of 5.00cm. Assuming its acceleration is constant:
part a) Determine the magnitude of the force exerted on the electron.
part b) Compare this force with the weight of the electron, which we ignored.
