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 position of the body

Text Solution

Verified by Experts

The correct Answer is:
A
Upthrust `= Vrho_("liquid")(g-a)`, where, a = downward acceleration, V = volume of liquid displaced
`"But for free fall a = g" " "therefore "Upthrust" = O `
