    Read the given statements and select the correct option.
    Statement 1: A pendulum can vibrate in an artificial satellite.
    Statement 2: Inside the satellite, acceleration due to gravity is zero.

    A) Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.

    B) Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.

    C) Statement 1 is true but statement 2 is false.

    D) Statement 1 is false but statement 2 is true.

    Correct Answer: D

    Solution :

    Inside the satellite, g = 0 \[\therefore T=2\pi \sqrt{\frac{I}{g}}=2\pi \sqrt{\frac{I}{0}}=\infty \] Thus, the pendulum will not oscillate.
