Question

How does the time period of a simple pendulum depend on the :
(i) length of pendulum
(ii) mass of bob?

Answer 1

Time period of a simple pendulum $\left(T\right)=2\pi \sqrt{\frac{l}{g}}$

$\left(i\right)T\propto \sqrt{l}$

$\left(ii\right)$ Time period of a simple pendulum does not depend on the mass of bob
