Summary:
specific gravity is the ratio of density of substance to the
density of water. First I calculated volume of the wood piece then
weight of the wood piece. And then I calculated weight of the
displaced ocean water. Which acts as buoyancy force. The difference
of buoyancy force and weight of wood will be equal to the tension
in the string.
