1 How fast is a 2642 eV electron moving?
2 A proton is accelerated (at rest) from a plate held at 45.3 volts to a plate at zero volts. What is the final speed?
3 What voltage is required accelerate an electron at rest to a speed of 9.4 x 106 m/s?
4 What voltage is required to stop a proton moving at a speed of 8.5 x 104 m/s?
