The buoyant force is equal to the mass of the water displaced which is Fb= rho V g. Be sure to convert cm^3 to m^3 if you're using rho = 1000
Surprised they didn't ask what the scale reads since they gave you the density of the rod.
A cylinder of length 5cm and uniform cross section area 50.24cm^2 is suspended from a spring balance and totally immersed in water.If the density of the material of the cylinder is 1.25g/m^3.
Determine the upthrust on the cylinder. Take g=10m/s^2
density of water=1000kg/m^3
