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 +7.11 x 10^{5} m/s to a final velocity of 2.21 x 10^{6} m/s while traveling a distance of 0.0678 m. The electron's acceleration is due to two electric forces parallel to the *x* axis: = 7.82 x 10^{-17} N, and , which points in the -*x* direction. Find the magnitudes of **(a)** the net force acting on the electron and **(b)** the electric force

Step 1

The acceleration of the of the electron is,

Step 2

a)

The required net ...
