In the following question, a statement of Assertion is followed by a statement of Reason. Assertion: When a body moves along a circular path, the work done by a centripetal force is zero. Reason: The centripetal force is utilised in moving the body along the circular path and hence the work is done. Choose one of the following statements is correct?

In the Bohr model of hydrogen atom, the electron is treated as a particle going in a circle with the centre at the proton. The proton itself is assumed to be fixed in an inertial frame. The centripetal force is provided by the Coloumb attraction. In the ground state, the electron goes round the proton in a circle of radius 5.3xx10^-11m . Find the speed of the electron in the ground state. Mass of the electron =9.1xx10^-31 kg and charge of the electron = 1.6xx10^-19C .

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 epsilon_0 is the vacuum permittivity, the speed of the electron is
