A cubical block of wood of edge 3 cm floats in water. The lower surface of the cube just touches the free end of a vertical spring fixed at the bottom of the pot. Find the maximum weight that can be put on the block without wetting it. Density of wood `=800kg//m^(3)` and spring constant of the spring `=50N//m`. Take `g=10m//s^(2)`
