Why the total energy of atomic electron is negative ?
The ratio of wavelength of a photon and that of an electron of same energy E will be
The total energy of electron in an atom is a combination of potential energy and kinetic energy. If total energy is -E for an electron in an atom, then its K.E. and P.E. respectively are
If the kinetic of revolving electron in an orbit is K, what is its potential energy and total energy ?
