Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

An electron is a subatomic particle (m = 9.11 x 10^-31 kg) that is subject to electric forces. An electron moving in the +x direction accelerates from an initial velocity of +5.81 x 10⁵ m/s to a final velocity of 2.69 x 10⁶ m/s while traveling a distance of 0.0663 m. The electron's acceleration is due to two electric forces parallel to the x axis: F1−→F1→ = 9.79 x 10^-17 N, and F2−→F2→, which points in the -x direction. Find the magnitudes of (a) the net force acting on the electron and (b) the electric force F2−→ .
