Ratio Of Charge To Mass For The Electron

Ratio of Charge to Mass for the Electron Introduction: The arse of this lab was to determine the measure of the ratio of an electron to its mass. This is do by accelerating a stream of electrons through a mensurable potential difference. The stream of electrons moves through a uniform magnetized field. It is perpendicular to the velocity of the electrons. The path of the electrons is circular because of this fact. The ratio of e/m can be found by the relationships amid the mensural accelerating potential difference, the diameter of the circular path describe by the electron, and the magnetic flux density.

Theory: British scientist Sir J.J . Thompson (1856-1940) start find that the electron was a discrete particle of electricity. From his discoveries came the genuine think of for e/m which is 1.75890*10^11 coulombs/kg. With this teaching we could therefore accurately determine the mass of the electron. The force F playing upon a charge that is movi...If you want to get a unspoiled essay, order it on our website: OrderEssay.net
