AIIMS 2000 Physics Collisions MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Two spheres of equal mass collide with the collision being absolutely elastic but not central. Then the angle between the velocities (θ) must be
A
θ = 180°
B
θ = 0°
C
90° ≤ θ ≤ 180°
D
θ = 90°
Correct Answer
Option D
Detailed Explanation
In an elastic collision, the angle between the velocities of two equal mass spheres after collision is 90° due to conservation of momentum and kinetic energy.
