Question

A body floats in a liquid contained in a beaker. If the whole system as shown in figure falls freely under gravity, then the upthrust on the body due to liquid is <img class="img-fluid question-image" alt="Question" src="https://cdn.tardigrade.in/q/nta/p-mfrcsclfe6vy5r9f.jpg" /> (A) Zero (B) Equal to the weight of liquid displaced (C) Equal to the weight of the body in air (D) None of these

Tardigrade Admin · Accepted Answer

Up thrust on the body =vσ g. For freely falling,body effective g becomes zero. So up thrust becomes zero

Q. A body floats in a liquid contained in a beaker. If the whole system as shown in figure falls freely under gravity, then the upthrust on the body due to liquid is

Zero

Equal to the weight of liquid displaced

Equal to the weight of the body in air

None of these

Up thrust on the body $= v σ g .$ For freely falling,body effective $g$ becomes zero. So up thrust becomes zero
