Dominik · Answer 1

The relative density is the ratio of a substance being measured with its reference which is usually water.

In hydrostatic weighing where force is involved, the formula to use is:

RD = Density in air / Density in air - Density in water

Therefore = 50/50-40 = 50/10 = 5

RD = 5N
