A body weights 0.26N in air. When totally immerse in water weight 0.16N and 0.18N in another liquid. Calculate the relative density of the liquid

To calculate the relative density of the liquid, we need to use the formula:

Relative density = (weight in air - weight in liquid)/(weight in air - weight in water)

Plugging in the given values, we get:

Relative density = (0.26 - 0.18)/(0.26 - 0.16) = 0.08/0.1 = 0.8

Therefore, the relative density of the second liquid is 0.8.
