NEET 2016 Physics Angular Acceleration MCQ Question
Type: MCQ-numerical-Medium-Class 11
A uniform circular disc of radius 50 cm at rest is free to turn about an axis which is perpendicular to its plane and passes through its centre. It is subjected to a torque which produces a constant angular acceleration of 2.0 rad s⁻². Its net acceleration in ms⁻² at the end of 2.0 s is approximately
A
6.0
B
3.0
C
8.0
D
7.0
Correct Answer
Option C
Detailed Explanation
The net acceleration is the tangential acceleration at the edge of the disc, calculated using a = αr, where α is the angular acceleration and r is the radius.
