JEE Main & Advanced Physics Simple Harmonic Motion Question Bank Assertion and Reason

  • question_answer
    Assertion             :       When a simple pendulum is made to oscillate on the surface of moon, its time period increases.  Reason                 :       Moon is much smaller as compared to earth.

    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: B

    Solution :

                \[T=2\pi \sqrt{\frac{l}{g}}.\] On moon, g is much smaller compared to g on earth. Therefore, T increases.
