Question

Select the height upto which the water level could rise after opening the valve.

• A.
• B.
• C.

Answer 1

The correct option is A

A liquid always seeks its own level. Hence, water would flow from the left beaker to the right. This happens until the level in the two beakers will become same. Since the volume is constant, water level finally in the left (and the right) beaker is less than the original height. Original height was $h_2$. So, final height can only be $h_1$ from the three given heights.
