Objects A and B of equal mass are lowered into a beaker of alcohol. It is found that object A sinks while object B floats. Explain which object has...

Archimedes' Principle states
that

Any
object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the
weight of the fluid displaced by the
object.

For an object to
float in a liquid it has to be buoyed up by a force exerted by the liquid that is
equivalent to the weight of the object.

Here object A and
object B have the same mass, but they differ in their volume. As object A sinks, it can
be inferred that the weight of the volume of alcohol displaced by object A less than the
weight of the object. On the other hand, object B floats in the alcohol implying that
the weight of alcohol displaced by object B is equal to the weight of the
object.

We can conclude that object B has a larger volume
compared to object A.
