An electron (mass = 9.11 X 10-31 kg) leaves one end of a TV picture tube with zero initial speed and travels in a straight line to the accelerating grid, which is 1.80 cm away. It reaches the grid with a speed of 3.00 X 106 m/s. If the accelerating force is constant, compute
(a) The acceleration;
(b) The time to reach the grid;
(c) The net force, in newtons. (You can ignore the gravitational force on the electron.)
