NEET 2022 Physics Conservation of Momentum MCQ Question
Type: MCQ-numerical-Medium-Class 11
A shell of mass m is at rest initially. It explodes into three fragments having mass in the ratio 2 : 2 : 1. If the fragments having equal mass fly off along mutually perpendicular directions with speed v, the speed of the third (lighter) fragment is:
A
2√2 v
B
3√2 v
C
v
D
√2 v
Correct Answer
Option A
Detailed Explanation
Using conservation of momentum, the third fragment's speed is calculated as 2√2 v.
