If a proton had a radius R and the charge was uniformly distributed, calculate using Bohr theory, the ground state energy of a H-atom when (i) R = 0.1, and (ii) R = 10 .
For a point nucleus in H-atom:
For an spherical nucleus of radius R,
If R < rB, same result.
If R >> rB: the electron moves inside the sphere with radius
r'B ( r'B= new Bohr radius).
