Homework Help: Tension and fluid type question

  1. Oct 19, 2005 #1
    I would appreciate any help I could get with this problem......

    A spherical-shaped hollow steel shell, with a radius of 2.5m, containing some instruments, is lowered by a cable into a lake. The shell with its contents weighs 7.2 x 10 to the 5th N on the deck of a ship from which it is being lowered. What is the tension in the cable when the sphere is completely immersed in the water?

    thanks
