Period of oscillation for a simple pendulum:

$\overline{){\mathbf{T}}{\mathbf{=}}\sqrt{\frac{\mathbf{l}}{\mathbf{g}}}}$

**A.**

The period is independent of the mass of the bob.

A simple pendulum consisting of a bob of mass m attached to a string of length L wings with a period T.

A. If the mass of the bob is reduced by half, what will the new period of oscillation be?

a. T/2

b. 2T

c. T/ √2

d. T

B. The pendulum is now swinging on Pluto. Express the new period of oscillation in terms of T (the period of the pendulum on Earth), knowing that the gravity on Pluto is 1/16 that of Earth.
