NEET 2016 Physics Buoyancy MCQ Question
Type: MCQ-conceptual-Hard-Class 11
Two non-mixing liquids of densities ρ and nρ (n > 1) are put in a container. The height of each liquid is h. A solid cylinder of length L and density d is put in this container. The cylinder floats with its axis vertical and length pL(p < 1) in the denser liquid. The density d is equal to
A
[²⁺ (n − 1)p]ρ
B
[¹⁺ (n − 1)p]ρ
C
[¹⁺ (n + 1)p]ρ
D
[²⁺ (n + 1)p]ρ
Correct Answer
Option B
Detailed Explanation
Using the principle of flotation and balancing the buoyant forces from both liquids, the density of the cylinder is derived.
