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 period T. Then T is equal to
- \(2 \pi \sqrt{\frac{\ell \rho}{(\rho-d) g}}\)
- \(2 \pi \sqrt{\frac{\ell d}{\rho g}}\)
- \(2 \pi \sqrt{\frac{\ell \rho}{d g}}\)
- \(2 \pi \sqrt{\frac{\ell d}{(\rho-d) g}}\)
Answer
(B) 2 d g
