The electric current \(I\) created by the electron in the ground state of \(H\) atom using Bohr model in terms of Bohr radius \(\left(a_{0}\right)\) and velocity \(\left(v_{0}\right)\) of electron in first orbit is:
1 \(\dfrac{e v_{0}}{2 \pi a_{0}}\)
2 \(\dfrac{2 \pi a_{0}}{e v_{0}}\)
3 \(\dfrac{2 \pi a_{0}}{v_{0}}\)
4 \(\dfrac{v_{0}}{2 \pi a_{0}}\)
Explanation:
In the ground state of hydrogen atom, suppose, \(a_{0}=\) Bohr radius. \(T=\dfrac{2 \pi a_{0}}{v_{0}}\) \(\therefore\) Current created, \(I=\dfrac{e}{T}=\dfrac{e v_{0}}{2 \pi a_{0}}\).

Assertion : Electrons in the atom are held due to coulomb forces. Reason : The atom is stable only because the centripetal force due to Coulomb's law is balanced by the centrifugal force.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Positive nucleus exhibits attractive coulomb force on electrons. Bohr's atomic model proposed electrons orbiting the nucleus without emitting radiation as long as they're in fixed (stationary) orbits. So correct option is (3).

Assertion : Bohr's atomic model cannot be used to explain multiple electron species Reason : It does not take inter-electronic interactions into account.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Bohr's atomic model, while successful for hydrogen, inadequately addresses multi-electron atoms or species due to its single-electron assumption and neglect of electron-electron repulsion. So correct option is (1).
