# Physics jee problem

A cubical block of side $$2a$$ when submerged till depth $$\dfrac a2$$ in a liquid of density $$k$$ is in equilibrium
1.What is the density of the block?
2.What is the time period of shm for small oscillations?
3.What happens if it is pushed completely vertically down?

Sort by:

The time period comes out to be 2pi× sq. root of (a/2g) · 1 year, 2 months ago

The density, of the block, should be given, in the terms of the density, of the water? · 1 year, 3 months ago

No need. It can be easily found by equating the buoyant force and the weight of the block. Density of the block is K/4. · 1 year, 2 months ago
