Two of the great mysteries of physics are the origin of mass, and the mysterious mass ratio between the proton and electron of ~1836. In this paper it is shown that the mass-energy of the proton is equivalent to the vacuum energy excluded by a spherical shell with an average radius ...

where mp is the proton mass, mn is the neutron mass, A=Z+N is the mass number, Z is the atomic number, N is the neutron number, and B(A,Z) is the nuclear binding energy. It is noted that atomic mass, if not stated differently, always refers to the mass of neutral atom. The...
The concept of electron acceleration by a laser beam in vacuum is attractive due to its seeming simplicity, but its implementation has been elusive, as it requires efficient electron injection into the beam and a mechanism for counteracting transverse ex
The mass of a proton is 1836 times that of an electron. If they fall through the same potential difference, find the ratio of their velocities. View Solution The mass of a H-atm is less than the sun f the masses of a proton and electron. Why is this? View Solution An atom of an...
The meaning of ELECTRON is an elementary particle consisting of a charge of negative electricity equal to about 1.602 × 10—19 coulomb and having a mass when at rest of about 9.109 × 10—31 kilogram or about 1/1836 that of a proton.
