Question

A block of wood floats in water with 3/10 of its length above water
If the block is made to float in salt solution of relative density
1 05 , find what fraction of its length is above salt solution

Pratyay Ghosh · Accepted Answer

density of wooddensity of water=1-310⇒density of wood=0
7 gm/cc

The fraction of length above the salt solution,
=1-density of wooddensity of salt water=1-0
71 05=13

A block of wood floats in water with 3/10 of its length above water. If the block is made to float in salt solution of relative density 1.05 , find what fraction of its length is above salt solution.
