MCQ (Single Correct Answer)

-1

A wooden cylinder of diameter $4 r$, height $h$ and density $\frac{\rho}{3}$ is kept on a hole of diameter $2 r$ of a tank, filled with water of density $\rho$ as shown in the figure. The height of the base of cylinder from the base of tank is H . IIT-JEE 2006 Physics - Properties of Matter Question 4 English Comprehension

If the height $h_2$ of water level is further decreased, then

cylinder will not move up and remains at its position.

for $h_2=\frac{h}{3}$, the cylinder again starts moving up

for $h_2=\frac{h}{4}$, the cylinder again starts moving up

for $h_2=\frac{h}{5}$, the cylinder again starts moving up.
