No effect

#### Explanation:

The time period of a simple pendulum is given by the expression

$T = 2 \pi \sqrt{\frac{L}{g}}$ " for "θ_0#<<$1$

The above equation is an approximation for the maximum angle that the pendulum swings away from the vertical called its amplitude being small.

We see that the expression is independent of the mass of the bob of the pendulum.
It is assumed that change of mass of the bob does not have any effect on the length of the pendulum.
