1. The problem statement, all variables and given/known data A hollow steel sphere of inner radius 0.9m and outer radius 1m is submeged 1000m below the surface of the sea. Take the density of water to be 1000 kg/m^3 and the density of steel to be 7.8 x 10^3. Calculate the tension in the wire to support the submerged sphere. 2. Relevant equations B = ρ(f)V(f)g W = mg 3. The attempt at a solution T + B = mg. Calculate T. Is this correct? The 1000m below sea level is what's making me doubt myself. Should this be factored into the calculation?
