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)
Weight of solid in air = 50 N
Weight of solid in water = 45 N
Buoyant force = Weight of water displaced = 50 N−45 N = 5 N
Density of water ρ = 1000 kg/m3
Acceleration due to gravity = 10 m/s2
Volume of solid = vs
Buoyant force = vsρg
Volume of solid vs = 5 N1000 kg/m3×10 m/s2 = 5×10−4 m3
