The period of simple pendulum does not change.

Explanation:

We can calculate the period of the simple pendulum with
T=2πlg formula.

Where T period , l length of cord, g acceleration of gravity

As you see , Period does not depend on mass of bob.

Therefore, the period of simple pendulum does not change.

Notice: We recommend that you review the article on the link discussing the variable-mass pendulum problem.
