Q2. A solid sphere made of metal whose density is 3000
kg/m3,and mass 3.2 kg is suspended by a cord.
(a)When the sphere is immersed in water what is the
tension in the cord?
(b)Now the cord is cut and the sphere is replaced by
one of the same size but density 700 kg/m3 . What
fraction of the sphere will be below the surface?
