In an electron microscope, there is an electron gun that contains two charged metallic plates 2.70 cm apart. An electric force accelerates each electron in the beam from rest to 8.70% of the speed of light over this distance. (Ignore the effects of relativity in your calculations.). Determine the kinetic energy of the electron as it leaves the electron gun. Electrons carry this energy to a phosphorescent viewing screen where the microscope's image is formed, making it glow. For an electron passing between the plates in the electron gun, determine the magnitude of the constant electric force acting on the electron. Determine the acceleration of the electron. Determine the time interval the electron spends between the plates. sourceCicondenser systemC2condenser aperturesample holdersampleobjective lensobjective apertureprojector systernimaging

Definition Definition Rate at which light travels, measured in a vacuum. The speed of light is a universal physical constant used in many areas of physics, most commonly denoted by the letter c . The value of the speed of light c = 299,792,458 m/s, but for most of the calculations, the value of the speed of light is approximated as c = 3 x 10 8 m/s.

1. How do you find the gravitational potential of two masses for any position around them that is outside the masses? Specifically, take the Earth and the Moon as an example. We need big masses like these because G is so small. Gravity is very weak. When we do electricity, we can work with smaller amounts of matter and smaller distances because electrical forces are stronger than gravitational forces. Here are the numbers https://nssdc.gsfc.nasa.gov/planetary/factsheet/moonfact.html MEarth = 5.97 × 1024 kg (Mass of Earth) MMoon = 7.35 × 1022 kg (mass of Moon) RE-M = 3.85 × 108 m (average separation of Earth and Moon centers) REarth = 6.378 × 106 m (radius of Earth) RMoon = 1.738 × 106 m (radius of Moon)
