If a body floats with `(m//n)^(th)` of its volume above the surface of water, then the relative density of the material of the body isA. `((n-m))/(n)`B. `(m)/(n)`C. `(n)/(m)`D. `((n-m))/(n)`

Answer» Correct Answer - A
Specific `=("weight of the body")/("force of buoancy")=(W)/(F_(B))=(d_(B))/(d_(W))`
`V_("in")=V-V_(out)=V-(m)/(n)V=V((n-m)/(n))`
`implies(V_(I n))/(V)=(d_(B))/(d_(W))=S.G`
