Question
In the Bohr’s atomic model, the electrostatic force of attraction between nuclear charge (Ze) and electron of charge e is balanced by the centripetal force acting towards the centre of atom. If ∈0 be the permittivity of vacuum and r be the radius of orbit in which electron is revolving, the speed of electron is
Options
A.$\sqrt{\frac{Ze^{2}}{\left( 4\pi \in_{o} \right)mrZe^{2}}}$
B.$\sqrt{\frac{\left( 4\pi \in_{0} \right)mr}{Ze^{2}}}$
C.$\sqrt{\left( 4\pi \in_{o} \right)mr}$
D.$\frac{e}{\sqrt{\left( 4\pi \in_{o} \right)mr}}$
