RE-NEET 2026 Physics Simple Harmonic Motion MCQ Question
Type: MCQ-conceptual-Medium-Class 11
A cylindrical cork of uniform density floats in a liquid of density ρ₁. If the cork is depressed slightly and released, it oscillates harmonically with time period T. If another liquid of the same cork floats in similar oscillation has time period 2T, then the value of ρ₂/ρ₁ is:
A
2
B
1/2
C
1/4
D
4
Correct Answer
Option C
Detailed Explanation
The time period of oscillation is inversely proportional to the square root of the density of the liquid. Therefore, if the time period doubles, the density must be one-fourth.
