Question

If two balls one of iron and the other of aluminum experiences same upthrust when dipped in water then, ___.

• A. both have equal volume.
• B. both have equal weight in air.
• C. both have a different volume.
• D. both have the same mass.

Answer 1

The correct option is A

both have equal volume.

The upthrust experienced by a body is independent of the weight of the body. It depends on the volume of the liquid displaced by the body which is equal to the volume of the body submerged. Here, since both experiences the same upthrust, therefore, both have equal volume.
