xxTIMURxx [149]

Answer:

False

Explanation:

The time period of a pendulum is given by :

T=2\pi \sqrt{\dfrac{l}{g}}

The terms used in the formula are :

l is length of pendulum

g is acceleration due to gravity

It is clear that the formula of time period of a pendulum is independent of its mass. So, the mass of the pendulum is not used to determine the time of a period. Hence, the given statement is false.
