  • STATEMENT-1: When a particle move along a straight line magnitude of its average velocity is equal to its average speed over any time interval provided particle does not return to path. STATEMENT-2: For one dimensional motion displacement and distance both are same.

    A
    Statement -1 is True, Statement-2 is Ture, Statement-2 is a correct explanantion for Statement-1.
    B
    Statement-1 is Ture, Statement-2 is Ture, Statement-2 is Not a correct explanantion for Statement-1.
    C
    Statement-1 is True, Statement-2 is False.
    D
    Statement-1 is False, Statement-2 is True.

  • Assertion: The average velocity of a particle is zero in a time interval. It is possible that the instantaneous acceleration is never zero in the interval. Reason: The magnitude of average velocity in an interval is equal to its average speed in that interval.

    A
    If both assertion `&` Reason are True `&` the Reason is a corrrect explanation of the Asserion.
    B
    If both Assertion `&` Reason are True but Reason is not correct explanation of the Assertion.
    C
    If Assertion is Trie but the Reason is False.
    D
    If both Assertion `&` Reason are false

  • Assertion : Magnitude of average velocity is equal to average speed, if velocity is constant. Reson : If velocity is constant, then there is no change in the direction of motion.

    A
    If both Assertion and Reason are correct and Reason is the correct explanation of assertion.
    B
    If both Assertion and Reason are correct but Reason in not the correct explanation of Assertion.
    C
    If Assertion is true but Reason is false.
    D
    If Assertion is false but Reason is true.
