An electron of mass 9.11×10?31 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 2.55 away. It reaches the grid with a speed of 2.60×106 . The accelerating force is constant. Find the acceleration. Find the Time to reach the grid. Find the Net force.
