" The period of simple pendulum does not change." The period of simple pendulum does not change.

Explanation:

"We can calculate the period of the simple pendulum with "We can calculate the period of the simple pendulum with
T=2 pi sqrt(l/g)" formula."T=2πlg formula.

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

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

"Therefore, the period of simple pendulum does not change."Therefore, the period of simple pendulum does not change.
