classical electron उदाहरण वाक्य

In 1956, he gained his Ph . D . in physics at Princeton University with a thesis on the classical electron a topic suggested by Fritz Rohrlich.
where e is the charge, uniformly distributed on the surface of a sphere, and a is the classical electron radius, which must be nonzero to avoid infinite energy accumulation.
In the case of the spherical membrane, classical equations of motion imply that the balance is met for the radius 0.75 r _ e where r _ e is the Classical electron radius.
This is consistent with the expected value of exactly zero . ( This should not be confused with the classical electron radius, which, despite the name, is unrelated to the actual size of an electron .)
If the Kerr Newman potential is considered as a model for a classical electron, it predicts an electron having not just a magnetic dipole moment, but also other multipole moments, such as an electric quadrupole moment.

The current limit is that an electron has no internal structure larger than 10-18 m, consistent with zero size and already 1000 times smaller than the classical electron radius . talk ) 00 : 15, 3 December 2011 ( UTC)
Where \ alpha is the fine structure constant, r _ e is the classical electron radius, Z is the atomic number of the material and P ( E, Z ) is some complex function that depends on the energy and atomic number.
:: : : : I think what you're trying to calculate is the classical electron radius, but you must have made a mistake since the answer ( according to the article ) is on the order of 10 " 15 m.
Incidentally, the value of that makes m _ { \ mathrm { em } } equal to the electron mass is called the classical electron radius, which ( setting q = e and restoring factors of and \ varepsilon _ 0 ) turns out to be
:: : From our article Classical electron radius : " In fact, modern particle physics experiments indicate that the electron is a point particle, i . e . it has no size and its radius is zero . " You can't get much smaller than that.
