Question

A stone weighing 200 g is dropped in a beaker and the water level in it rises to 400 ml. g is required for 200 ml rise in water level.

• A. 400
• B. 100
• C. 250

Answer 1

The correct option is B 100

More will be the weight higher will be the rise in water level.
400 ml rise in the water level occurs with = 200 g
200 ml is half of the water level rise of previous case
so half of the weight is required for 200 ml rise that is
200 g x $\frac{1}{2}$= 100 g
