    Suppose the amplitude of a simple pendulum having a bob of mass m is θ0. Find the tension in the string when the bob is at its extreme position.
    Ans : Let T be the tension in the string at the extreme position.
    Velocity of the pendulum is zero at the extreme position.
    So, there is no centripetal force on the bob.
    ∴ T = mgcosθ0
