Question

When a stone of mass 200g is completely immersed in a beaker carrying full
of water, 50gof water is overflowed. What will be the weight of the stone in water ?

Answer 1

Answer:

decreases once the stone is lowered in water, it means that some force acts on the stone in upward direction. As a result, the net force on the string decreases and hence the elongation also decreases. As discussed earlier, this upward force exerted by water is known as the force of buoyancy

Explanation:

If 120 ml of water is displaced means, volume of stone is 120 ml. weight of stone in water = volume×(ρs - ρw)g = 120×(ρs - ρw)g gram.
