AIPMT PRELIMS 2003 Physics Conservation of Momentum MCQ Question
Type: MCQ-numerical-Medium-Class 11
A stationary particle explodes into two particles of masses m₁ and m₂ which move in opposite directions with velocities v₁ and v₂. The ratio of their kinetic energies E₁/E₂ is :
A
m₂/m₁
B
m₁/m₂
C
1
D
(m₁v₁/m₂v₁)
Correct Answer
Option A
Detailed Explanation
The kinetic energy ratio can be derived using the formula E = 1/2 mv² and the conservation of momentum, which gives m₁v₁ = m₂v₂.
