  • question_answer
    A simple pendulum oscillates in air with time period T and amplitude A. As the time passes

    A) T and A both decrease

    B) T increases and A is constant

    C) T remains same and A decreases

    D) T decreases and A is constant

    Correct Answer: C

    Solution :

    [c] When a simple pendulum oscillates in air continuously then its time period remains same whereas amplitude decreases.
