What is the relationship between gravitational force, mass, and distance?

The gravitational force between two point masses is given by:

F = GMm/r²

F is the gravitational force, M and m are the masses, and r is the distance between the masses.

Explanation:

The question says that, "Calculate the absolute density of a fluid whose mass is 12.8 kg and which occupies a volume of 16.3 cm³".

Mass, m = 12.8 kg = 12800 g

Volume, V = 16.3 cm³

The density of an object is defined as the mass per unit volume i.e.

So, the absolute density of the fluid is equal to .
