A wooden cube (density of wood d) of side l floats in a liquid of density ρ with its upper and lower surfaces horizontal.

Question 1

A wooden cube (density of wood d) of side l floats in a liquid of density ρ with its upper and lower surfaces horizontal. If the cube is pushed slightly down and released, it performs simple harmonic motion of **, T. Then, T is equal to

Question 2

Correct Option (b)

Explanation:

Let at any instant, cube be at a depth x from the equilibrium position, then Net force acting on the cube = Upthrust on the portion of length x

Negative sign shows that force is opposite to x . Hence, equation of SHM

F =- kx ......(ii)

Comparing Eqs. (i) and (ii), we get
