The relative density of the liquid, given that it can support the column of water is a. 0.5
How to find the relative density ?
The pressure at a depth in a fluid is given by:
Pressure = Density × gravitational acceleration (g) × Height
For both the liquid and the water, the pressure is the same (since they are at the same depth), so we can set up an equation:
Density of the Liquid × g × 30 cm = Density of Water × g × 60 cm
Density of the Liquid × 30 cm = Density of Water × 60 cm
Find the relative density:
RD = Density of the Liquid / Density of Water = (30 cm / 60 cm)
= 0.5
In conclusion, the relative density of the liquid is 0.5. This means that the liquid is half as dense as water.
