Answer / Solution

UNSOLVED

Calculate the binding energy per nucleonm in MeV and the packing fraction of an alpha particle. Given Mass of proton=1.0080u, Mass of neutron=1.0087u and mass of alpha particle=4.0026u.

Answer / Solution

UNSOLVED

State any three limitation of Bohr`s model of the hydrogen atom.

Answer / Solution

UNSOLVED

In a hydrogen atom model , an electron of mass m and charge e revolves around the nucleus in a circular orbit of radius r. Develop an expression for the radius r of the orbit in terms of m,e,, the quantum number n, Planck constant h and the permittivity of free space and hence, use their values to find the Bohr`s radius.
