The force between two electrons when placed in air is equal to 0.5 times the weight of an electron,If mass of the electron is `9.1times10^(-31)kg` ,the force between the two electrons is

The force between an electron and a proton is

If mass of an electron is 9.1xx10^(-31) kg, the number of electrons in 1 mg is

The rest mass of an electron is 9.11xx10^(-31) kg. Molar mass of the electron is

If mass of an electron is 9.11xx10^(-31) kg, how many electrons will weight 2 kg?

If the mass of an electron is 9 xx 10^(-28) grams weight of one mole of electron is

The mass of an electron is 9.11xx10^(-31)kg . How many elecrons would make 1kg?

Determine the de Broglie wavelength of a proton, whose kinetice energy is equal to the rest of the mass energy of an electron. Given that the mass of an electron is 9xx10^(-31) kg and the mass of a proton is 1837 times as that of the electron.
