Question

Some parameters of a simple pendulum are altered which resulted in a change in its time period. Which of the following cannot be those parameters?

• A. Mass of the bob
• B. Length of the string
• C. Material of the bob
• D. Location of the pendulum

Answer 1

Answer: (A), (C)

Material of the bob

The time period of a simple pendulum is directly proportional to the square root of the length of its string, and is inversely proportional to the square root of the acceleration due to gravity at the place. So, a change in the mass and/or the material of the bob of the pendulum cannot alter its time period.
