In a TV, electrons with a speed of 7.31 x 107 m/s strike the screen from behind, causing it to glow. The electrons come to a halt after striking the screen. Each electron has a mass of 9.11 x 10-31 kg, and there are 7.97 x 1016 electrons per second hitting the screen over an area of 2.15 x 10-7 m2. What is the pressure that the electrons exert on the screen? Hi, can anyone help me please? I really dont know how to start this question. It confuses me a lot.
