Question

a body floats in liquid contained in a beaker . if the whole system falls under gravity then the up thrust on the body is​

Answer 1

Answer:

As we know When the beaker is permitted to fall naturally, the body's visible weight becomes zero, implying that the body exerts no impact on the water. As a result, no water is displaced because of the body's weight. Therefore, the buoyant force, or upthrust, would be zero

Answer 2

Explanation:

zero.

When the beaker is allowed to fall freely, apparent weight of the body becomes zero i.e. body exerts no force on water. Hence no water is displaced due to weight of the body. So buoyant force i.e. upthrust will also become zero.
