An electron of mass 9.11×10?31kg leaves one end of a TV picture tube with zero initial speed and travels in a straight line to the accelerating grid, which is a distance 1.30cm away. It reaches the grid with a speed of 2.50×106m/s . The accelerating force is constant.
Find the acceleration.
Find the time to reach the grid.
Find the net force. (You can ignore the gravitational force on the electron).
