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.
