Solution
Correct Answer:
1.0 m
- Fundaμental Formula: The period of a simple pendulum for small oscillations is T=2πgL.
- Given: T=2 s and g=10 m/s2.
- Isolate Length (L):
- 2=2π10L
- 1=π10L
- π1=10L⟹π21=10L.
- Numerical Approximation: Since π2≈9.87≈10:
- L≈1010=1.0 m.
- Note: A pendulum with a period of exactly 2 seconds is called a Seconds Pendulum.
