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

  • question_answer
    Assertion          :           A body, whatever its motion is always at rest in a frame of reference which is fixed to the body itself. Reason            :           The relative velocity of a body with respect to itself is zero.

    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 :

                    A body has no relative motion with respect to itself. Hence if a frame of reference of the body is fixed, then the body will be always at relative rest in this frame of reference.
