Physics-Bohr Model

NEET Physics Bohr Model MCQ Question

Type: MCQ-numerical-Easy-Class 12

In the Bohr model, what is the frequency of the electron revolving around a proton in a hydrogen atom if the radius of the orbit is 5.3 × 10^–11 m and the velocity of the electron is 2.2 × 10^6 m/s?

A

6.6 × 10^15 Hz

B

8.2 × 10^14 Hz

C

1.5 × 10^15 Hz

D

5.0 × 10^15 Hz

Correct Answer

Option A

Detailed Explanation

The frequency of the electron is given by v/(2πr), where v is the velocity and r is the radius. Substituting the given values results in 6.6 × 10^15 Hz. This aligns with the example provided in the NCERT context.
