1. 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 6.80 X 10⁵ m/s in a distance of 4.00 cm. Assume its acceleration is constant.

(a) Determine the magnitude of the force exerted on the electron.

(b) Compare this force (F) with the weight of the electron (_Fg), which we ignored. F/F_g= 7.

2. Two forces F₁ and F₂ act on a 7.80-kg object. F₁ = 40.0 N and F₂ = 11.0 N.
