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

A

(a) zero

B

(b) equal to the weight of the liquid displaced

C

(c) equal to the weight of the body in air

D

(d) equal to the weight of the immersed portion of the body

Text Solution

Verified by Experts

The correct Answer is:
A
The whole system falls freely under gravity
Upthrust = weight of fluid displaced
=(mass of fluid displaced)xg
For a freely falling body, `g=0`
`:. Upthrust=0`
