An electron of mass 9.11×10^−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 a distance 1.40 cm away. It reaches the grid with a speed of 4.0×10^6 m/s. The accelerating force is constant.
A)Find the acceleration. (m/s)
B)Find the time to reach the grid. (s)
C)Find the net force. (You can ignore the gravitational force on the electron). (N)
