A Simple Pendulum That Consists of a Small Ball of Mass

Multiple Choice

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.
