A body floats in a liquid contained in a beaker. The whole system as shown falls freely under gravity. The upthrust on the body due to the liquid is

A

zero

B

equal to the weight of the liquid displaced

C

equal to the weight of the body in air

D

equal to the weight of the immersed portion of the body

Text Solution

Verified by Experts
