A simple pendulum of length on Earth () is transported to the Moon, where gravitational acceleration is . By what factor does its period of oscillation increase?
Answer and explanation
Correct answer: B.
- Step 1: Period formula: .
- Step 2: Ratio of periods: .
- Step 3: Substitute values: .
Answer
sqrt(6) approx 2.45.
Why not the others: '' forgets the square root; '' is Moon gravity; '' is an overestimate.
