STANDARD Physics Bohr's Model MCQ Question

Type: MCQ-conceptual-Medium-Class 11

The electric current I created by the electron in the ground state of H atom using Bohr model in terms of Bohr radius (a₀) and velocity of electron in first orbit v₀ is

A

ev₀/2πa₀

B

2πa₀/ev₀

C

2πa₀/v₀

D

v₀/2πa₀

Correct Answer

Option A

Detailed Explanation

In the ground state of hydrogen atom, the time taken by electron to complete one revolution is T = 2πa₀/v₀. The current created is I = charge/time = ev₀/2πa₀.
