A simple pendulum having a bob of mass M has a period T. If you double M but change nothing else, what would be the new period?
A)2T
B)T $\sqrt { 2 }$
C)T
D)T/ $\sqrt { 2 }$
E)T/2

Question

Quizplus · Accepted Answer

The period of a simple pendulum is independent of the mass of the bob. It depends only on the length of the pendulum and the acceleration due to gravity. Therefore, doubling the mass does not change the period, so the new period remains T.
