In the Bohr model of a hydrogen atom, the centripetal force is furnished by the coulomb attraction between the proton and the electron. If $${{a}_{0}}$$is the radius of the ground state orbit, m is the mass, e is the charge on the electron and $${{\varepsilon }_{0}}$$is the vacuum permittivity, the speed of the electron is [CBSE PMT 1998]
