An electron (mass = 9.11 X 10*1 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 2.70cm away. It reaches the grid with a speed of 3.30 X 10°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. Ignore the gravitational force on the electron.
