An electron of mass 9.11 10-31 kg has an initial speed of 2.80 105 m/s. It travels in a straight line, and its speed increases to8.00 105 m/s in a distance of 4.80 cm. Assume its acceleration is constant.
(a) Determine the magnitude of the force exerted on the electron.
N
(b) Compare this force (F) with the weight of the electron (Fg), which we ignored.
F/Fg
