JEE Main & Advanced Physics Work, Energy, Power & Collision / कार्य, ऊर्जा और शक्ति Question Bank Assertion and Reason

  • question_answer
    Assertion          :           A quick collision between two bodies is more violent than slow collision, even when initial and final velocities are identical. Reason            :           The rate of change of momentum determine that force is small or large.

    A) If both assertion and reason are true and the reason is the correct explanation of the assertion.

    B)             If both assertion and reason are true but reason is not the correct explanation of the assertion.

    C)             If assertion is true but reason is false.

    D)             If the assertion and reason both are false.

    E)             If assertion is false but reason is true.

    Correct Answer: A

    Solution :

    In a quick collision, time t is small. As \[F\times t=\]constant, therefore, force involved is large, i.e. collision is more violent in comparison to slow collision.
