If the natural frequency of a spring mass system on earth is f, its natural frequency on moon where acceleration due to gravity is one-sixth of that on earth will be
- A. f/6
- B. 6f
- C. f/$\sqrt{6}$
- D. f
Answer: D. f
Explanation: Natural frequency f = (1 / 2*pi) * $\sqrt{k/m}$. It does not depend on gravity, so it remains the same on Earth and the moon.
