(C) Heavier than water
<u>Explanation:</u>
Given
Diameter of the rod is uniform
The road is floating in a liquid.
Let the area of cross-section of the rod = A
Let the weight density of water = γw
Let the weight density of liquid = γl
Let the density of water = ρw
g is the gravitational force
So, weight of rod = density of the rod X volume
Wrod = ρw X g X ( A X 2L) + 2 ρwg (A X L)
Wrod = 4ρwgAL
Wrod = 4γwAL
We can see that the weight of the rod is more than the density of water. So, in water, the rod will sink.
If the rod is floating on the liquid then the liquid is heavier than the water.
Therefore, The liquid is heavier than the water.
