NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Hard-Class 11
Consider two equal spherical masses undergoing a glancing elastic collision where one is initially at rest. After the collision, they move at right angles to each other. Which of the following accurately describes a condition for this outcome?
A
Collision occurs only when the bodies touch each other.
B
One mass must be significantly larger than the other.
C
The collision must involve a third mass nearby.
D
The masses must be moving in parallel before collision.
Correct Answer
Option A
Detailed Explanation
The NCERT context describes that the simplification arises when spherical masses with smooth surfaces collide only when they touch each other, leading to right-angle movement after collision.
