NEET Physics Angular Momentum MCQ Question
What condition must be satisfied for the total linear momentum of a system to be conserved during a collision?
The net external force acting on the system must be zero.
The masses of the colliding objects must be equal.
The collision must be elastic.
The objects must collide at a right angle.
Correct Answer
Detailed Explanation
The total linear momentum of a system is conserved when the net external force acting on the system is zero, as stated in the context of collisions and Newton's third law.
