NEET Physics Angular Momentum MCQ Question
Which of the following statements about angular momentum and its conservation during collisions is correct?
Angular momentum is conserved only in elastic collisions regardless of external forces.
The total linear momentum is conserved in all types of collisions, including elastic and inelastic.
Angular momentum can change if there is an external torque acting on the system.
All collisions conserve angular momentum regardless of the mass or speed of the objects involved.
Correct Answer
Detailed Explanation
Statement B is correct as it reflects the principle of conservation of linear momentum, which holds true in all collisions. Statement A is incorrect because angular momentum can also be conserved in inelastic collisions if no external torque acts. Statement C is correct, but it does not encompass the conservation principle. Statement D is misleading as angular momentum conservation depends on external torques present.
