A body floats in a liquid contained in a beaker. The whole system as shown in the figure falls freely under gravity. The upthrust on the body is
equal to the weight of the liquid displaced.
equal to the weight of the body in air.
equal to the weight of the immersed portion of the body.
The correct option is A 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.
