Question

Quizplus · Accepted Answer

When the stone is suspended in the water by a string, it displaces a volume of water equal to its own volume. This displacement causes an increase in the buoyant force acting on the stone, but since the stone is held by a string and not floating freely, this force does not directly affect the stone's apparent weight. However, the displaced water exerts an equal and opposite force on the rest of the water and the container, effectively transferring the weight of the stone to the scale through the water. Therefore, the scale reading increases by an amount equal to the weight of the stone.
