The time period of a pendulum –
- ADepends on the mass
- BDepends on its length
- CDepends on time
- DDepends on temperature
Show answer and explanation
Correct answer: (b) Depends on its length
Explanation
The time period of a simple pendulum is T = 2π√(l/g): it depends on its length (l) and on gravity (g).
It does not depend on the mass of the bob, or (for small swings) on how far it swings.
