A simple pendulum that consists of a small ball of mass m and a massless wire of length L swings with a period T
Suppose now that the mass is rearranged so that mass of the ball was reduced but the mass of the wire was increased, with the total mass remaining m and the length being L. What is true about the new period of swing? (There could be more than one correct choice.) A) The new period is T because the total mass m has not changed. B) The new period is T because the length L has not changed. C) The new period is greater than T. D) The new period is less than T E) The new period is T because neither L nor m have changed.
