A wooden block of volume 5.23×10−4 m3 floats in water, and a small steel object of mass m is placed on top of the block. When m=0.320 kg, the system is in equilibrium and the top of the wooden block is at the level of the water. (Take the density of steel to be 8 g/cm3.) (a) What is the density of the wood? kg/m3 (b) What happens to the block when the steel object is replaced by an object whose mass is less than 0.320 kg ? The block will float higher in the water. The position of the block will remain unchanged. The block will sink slightly. The block will sink to the bottom. (c) What happens to the block when the steel object is replaced by an object whose mass is 0.390 kg ? The block will float higher in the water. The position of the block will remain unchanged. The block will sink slightly. The block will sink to the bottom.
