NEET 2022 Physics Angular Acceleration MCQ Question
Type: MCQ-numerical-Medium-Class 11
The angular speed of a fly wheel moving with uniform angular acceleration changes from 1200 rpm to 3120 rpm in 16 seconds. The angular acceleration in rad/s² is:
A
12π
B
104π
C
2π
D
4π
Correct Answer
Option A
Detailed Explanation
Using the formula for angular acceleration α = (ω₂ - ω₁)/t and converting rpm to rad/s, the angular acceleration is calculated as 12π rad/s².
