AIIMS 2019 Physics Elastic Collisions Assertion Reason Question
There is no loss in energy in elastic collision and Linear momentum is conserved in elastic collision.
Both assertion and reason are true and reason is the correct explanation of assertion.
Both assertion and reason are true but reason is not the correct explanation of assertion.
Assertion is true but reason is false.
Assertion is false but reason is true.
Correct Answer
Detailed Explanation
Option B is correct because both the assertion and the reason are true: in an elastic collision, kinetic energy is conserved, and linear momentum is also conserved. However, the reason does not directly explain the assertion, as conservation of momentum applies to all types of collisions, not just elastic ones. Option A is incorrect because, while both statements are true, the reason does not explain the assertion. Options C and D are incorrect because they misrepresent the truth of the statements; both the assertion and reason are indeed true. Understanding these principles is crucial in analyzing collisions in physics, where the conservation laws play a fundamental role.
