The time of oscillation of a floating body is _________________?
Correct answer: D. None of these
- A. Longer, if Metacentric height is increased
- B. Independent of the Metacentric height
- C. Dependent on the buoyant forces only
- D. None of these
Explanation
For small oscillations of a floating body, the period varies approximately as T ∝ 1/√(GM), so increasing metacentric height makes the oscillation faster and the period shorter. It is therefore not longer, independent, or determined by buoyant force alone.
