Question

6. If two metal cubes A and B of same mass have density in the ratio of 2:1, which metal cube
will have more upthrust when immersed in same liquid?
a. Cube A
b. Cube B
c. Same for both the cubes
d.cannot be determined​

Answer 1

Answer:

If two metal cubes A and B of same mass have density in the ratio of 2 : 1, then CubeA [0ptionA] will have more upthrust when immersed in same liquid.

Explaination:

According to the question,

⟹ Mass of cube A = m₁

⟹ Mass of cube B = m₂

It is given that, both the cubes are having same mass. So :

⟹ m₁ = m₂

The ration of their densities is :

⟹ d₁ : d₂

⟹ 2 : 1

We know that, greater the density results in greater upthrust.

So, cube A is having more density than compared to cube B.

⟹ d₁ > d₂

Therefore, cube A will have more upthrust when immersed.
