(a). The density of the object is 1382 kg/m³.
(b). The density of the oil is 536.4 kg/m³.
Explanation:
Given that,
Weight in air = 79.1 N
Weight in water = 21.8 N
Weight in oil = 48.4 N
We need to calculate the volume of object
Using formula of buoyant force
Put the value into the formula
We need to calculate the density
Using formula of buoyant force
The density of the object is 1382 kg/m³.
(b). We need to calculate the volume of object
Using formula of buoyant force
We need to calculate the density
Using formula of buoyant force
The density of the oil is 536.4 kg/m³.
Hence, This is the required solution.
