Three forces act on an object, considered to be a particle, which moves with constant velocity v = (3i ^ − 2j ^ ) m/s. Two of the forces are F→1 = (3i ^ + 5j ^ − 6k ^ ) N and F→2 = (4i ^ − 7j ^ + 2k ^ ) N. Find the third force.

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 +7.67 x 105 m/s to a final velocity of 2.57 x 106 m/s while traveling a distance of 0.0857 m. The electron's acceleration is due to two electric forces parallel to the x axis: = 7.62 x 10-17 N, and , which points in the -x direction.
