AIIMS 2001 Physics Torque and Angular Acceleration MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Two masses are attached to a rod end to end. If torque is applied they rotate with angular acceleration α. If their distances are doubled and same torque is applied, then they move with angular acceleration
A
4α
B
α
C
3α
D
α/4
Correct Answer
Option D
Detailed Explanation
Torque τ = Iα, where I is the moment of inertia. Doubling the distance quadruples I, so α is reduced by a factor of 4.
