## Homework Statement

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.

## Homework Equations

B = ρ(f)V(f)g

W = mg

## 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?
