The length of a simple pendulum is increased four times to its previous value while the mass is doubled. What is the ratio of the new and previous time period of the pendulum ?
- A. 3:1
- B. 2:5
- C. 2:1 ✓
- D. 3:2
Correct Answer: C. 2:1
Explanation
The time period of a simple pendulum depends on the square root of its length and is independent of mass. Increasing the length by four times doubles the time period.
