AIPMT PRELIMS 2003 Physics Conservation of Angular Momentum MCQ Question
Type: MCQ-conceptual-Medium-Class 11
A thin circular ring M and radius ‘r’ is rotating about its axis with a constant angular velocity ω. Four objects each of mass m, are kept gently to the opposite ends of two perpendicular diameters of the ring. The angular velocity of the ring will be -
A
Mω/4m
B
Mω/(M + 4m)
C
(M + 4m)ω/M
D
(M + 4m)ω/(M + 4m)
Correct Answer
Option B
Detailed Explanation
Using the conservation of angular momentum, the initial angular momentum equals the final angular momentum, allowing us to solve for the new angular velocity.
