Question

Which of the following factors affect the time period of a pendulum?

• A. Length of the pendulum
• B. The acceleration due to gravity at that place
• C. Mass of the bob
• D. None of these

Answer 1

Answer: (A), (B)

The correct options are
A Length of the pendulum
B The acceleration due to gravity at that place

The following are the factors which affect the time period of a pendulum :
(a) Length (I) - The time period is directly proportional to the square
root of its length i.e., T $\propto \sqrt{I}$
(b) Acceleration due to gravity (g) - Time period is inversely proportional
to the square root of the acceleration due to gravity at the place i.e.,
T $\propto \frac{I}{\sqrt{g}}$
The time period of a simple pendulum is independent of the mass of its
bob and also of the nature of the material of the bob
