Solve the following example : A body of volume 100 cm^3 is immersed completely in water. Find the weight of the water displaced by the body. [g = 9.8 m//s^2, rho(water) = 10^3 kg//m^3]

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)`
