NEET 2026 Physics question
A cylindrical cork of uniform density floats in a liquid of density . If the cork is depressed slightly and released, it oscillates harmonically with time period . If the same cork floats in another liquid of density , then the similar oscillation has time period . The value of is:
Answer: (4)
Solution
If the cork (mass , cross-section ) is pushed down by , the extra buoyant force is , so the restoring constant is and \sqrt\frac{m}${ρ A
