Consider an atom with atomic number Z as consisting of a positive point charge at the centre and surrounded by a distribution of negative electricity uniformly distributed within a sphere of radius R. The electric field at a point inside the atom at a distance r from the centre is

Answer»

`(ZE)/(4pi epsilon_(0))[(1)/(r^(2))-( r )/(R^(3))]`
`(Ze)/(4pi epsilon_(0))[(1)/(r^(2))+(1)/(R^(3))]`
