A solid block of volume V and density ρ5 floats on a liquid of density ρ. How much force should be applied over the block to completely submerge it under water? (Given: g=10 m/s2,ρ=103 kg/m3,V=10 m3)
A solid weighs 50 N in the air and 45 N when completely immersed in water. Density of water ρ = 1000 kg/m3. Calculate the volume of the solid.
(Take acceleration due to gravity = 10 m/s2)
