NEET Physics Kinetic Energy MCQ Question
Consider a scenario where a neutron undergoes an elastic collision with a deuterium nucleus, which has a mass twice that of the neutron. If the initial velocity of the neutron is v_1i and its final velocity after the collision is v_1f, what is the fractional kinetic energy lost by the neutron?
1/9
1/2
3/4
2/3
Correct Answer
Detailed Explanation
For deuterium, m_2 = 2m_1, leading to a fractional kinetic energy loss of f_1 = 1/9 as derived from the provided equations.
