A wooden block is tied to a metallic rod of mass 100 g and immersed completely inwater. When the displaced water is collected in water. |
|
Answer» Solution :Mass of the metallic rod = 100 g Volume of the metallic rod + volume of WOODEN BLOCK = 400 ml Density of the metallic rod = 5 g `cm^(-3)` Volume of the metallic rod =` massof the metallic rod/density of the rod`=`8/1=n^(3)/1,n^(3)=8, n=2` Volume of wooden the block = `400-20 = 380 cm^(3)` Mass FO the wooden block =`"mass"/"volume"=300/380=0.79" g "cm^(-3)` |
