  • question_answer
    Direction: For questions given below two statements are given-one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the codes [a], [b], [c] and [d] as given below.
    Assertion No force is required by the body to remain in any state.
    Reason In uniform linear motion, acceleration has a finite value.

    A) Both A and R are true and R is correct explanation of the A.

    B) Both A and R are true but R is not the correct explanation of the A.

    C) A is true but R is false.

    D) A is false but R is true.

    Correct Answer: C

    Solution :

    A is true but R is false.
    Force is required to change the state of the body.
    In uniform motion body moves with constant speed so acceleration should be zero.
