Question 23
Simple Harmonic MotionA simple pendulum, 0.6 m long, has a period of 1.5 s. What is the period of a similar pendulum 0.4 m long in the same location?
- A.1.5√(2/3) s
- B.1.5√(3/2) s
- C.2.25 s
- D.1.00 s
- E.2.00 s
Show the answer and explanation
Answer: A (1.5√(2/3) s)
Explanation
T is proportional to √L, so T₂ = 1.5 × √(0.4/0.6) = 1.5√(2/3) s.
