An electron is 10 cm to the left of a +2 ?C point charge, and 10 cm to the right of a -2 C point charge. The +2 C and the -2 C charges are fixed in position and together with the electron lie along the x-axis. When the electron, which is free to move, is released from rest, it accelerates along the x-axis toward the +2 C point charge. Determine the velocity of the electron when it is 5 cm to the left of the +2 C point charge.
A 2.47 kg steel ball strikes a massive wall at 11.7 m/s at an angle of alpha = 67.2° with the plane of the wall. It bounces off with the same speed and angle. If the ball is in contact with the wall for 0.218 s, what is the magnitude of average force..
