Question
Consider an object that floats in water but sinks in oil. Assume the density of the oil is 0.80 g/cm3. When the object floats in water, half of it is submerged. If we slowly pour oil on top of the water so that it completely covers the object, the object
a. move up
b. stay the same
c. move down
Consider an object that floats in water but sinks in oil. Assume the density of the oil is 0.80 g/cm3. When the object floats in water, half of it is submerged. If we slowly pour oil on top of the water so that it completely covers the object, the objectExplanation / Answer
The object will be move up.
the volume of the object submerged will be < the volume of objects submerged in water only.
This is so, as some additional upthrust is provided by the oil also. So, the water ahs to provide less. Less immersion in water.
