JEE Main & Advanced Physics Motion in a Straight Line / सरल रेखा में गति Question Bank Assertion and Reason

  • question_answer
    Assertion          : A body can have acceleration even if its velocity is zero at a given instant of time. Reason            :           A body is momentarily at rest when it reverses its direction of motion.           

    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 :

                    When body going vertically upwards, reaches at the highest point, then it is momentarily at rest and it then reverses its direction. At the highest point of motion, its velocity is zero but its acceleration is equal to acceleration due to gravity.
