What is electron rest mass??

Question

What is electron rest mass??

Answer 1

it's the mass of an electron as measured when its speed is zero relative to an observer

Answer 2

Electron rest mass:  9.109 X 10^(-31) kg

Answer 3

The existence of the neutrino was originally suggested by Pauli to account for the wide range of energies possessed by electrons emitted in the process of β-decay of a particular radioactive species. Such a particle must have zero charge and a rest mass very much less than that of the electron.

Answer 4

Type "mass of electron" into Google.

Answer 5

The electron rest mass(m_e)  is the mass of an electron as measured when its velocity is zero relative to an observer electron rest mass= 9,1 x 10 ^ -31 kg.

It's also used as a unit of mass.

Answer 6

......

Answer 7

me = 9.109 * 10 ^-31 kg
