RE-NEET 2026 Physics Angular Momentum MCQ Question
Type: MCQ-conceptual-Medium-Class 11
A thin horizontal disc is rotating about a vertical axis passing through its fixed centre O. Its angular momentum is Lₐ and Lᵦ computed about points A and B, respectively, with OB = 2 × OA. The value of Lₐ/Lᵦ is:
A
1/2
B
1
C
2
D
1/4
Correct Answer
Option B
Detailed Explanation
Angular momentum depends on the distance from the axis of rotation. Since OB = 2 × OA, the angular momentum about B is the same as about A.
