An electron of mass 9.11 x 10-31 kg has an initial speed of 4.00 x 105 m/s. It travels in a straight line, and its speed increases to 7.60 x 105 m/s in a distance of 4.20 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 (F), which we ignored. F ܗܝ| ܝ
