Question

the buoyancy of stone in water is 0.5N. what about the same stone in kerosene​?if weight of stone in water is 1N and 1.5N in air.
justify your answer.​

Answer 1

Answer:

The buoyancy of the same stone in kerosene,

B = 1.54×10⁸ N

Explanation:

Let,

The volume of the stone = V

we know,

The density of kerosene, ρ = 800 kg/m³

The density of water = 1000 kg/m³

$B = Vρ \: g$

According to the question,

0.5 = V × 1000 × 9.8

V = 1.96×10⁴ m³

Again,

The buoyancy of the same stone in kerosene,

B = Vρg = (800 × 9.8 × 1.96×10⁴) = 1.54×10⁸ N
