Question

A stone weighing 200 g is dropped in the given beaker, the water level in it rises to 400 ml. What would have been the rise in water level if a stone weighing 300 g instead of 200 g, would have been dropped in the beaker?

• A. 200 ml
• B. 3000 ml
• C. 100 ml
• D. 300 ml

Answer 1

The correct option is D 300 ml

Initial water level in the beaker = 200 ml.
Water level in the beaker after dropping a 200 g of stone in it = 400 ml.
So, the rise in water level = 400 ml - 200 ml = 200 ml.
Rise in water level for 200 g stone = 200 ml.
Rise in water level for each g of stone = 1 ml.
Rise in water level for 300 g stone = 1 x 300 = 300 ml.
So, the water level would have risen by 300 ml.
