When a body lighter than water is completely submerged in water, the buoyant force acting on it is found to be `n` times its weight. The specific gravity of the specific gravity of the material of the body is

Options

A. `(1)/(1+n)`
B. `(1)/(n)`
C. `n`
D. `n+(1)/(n)`

Answer

B

Explanation

`Vrho_(w)g=nmg`
`impliesVrho_(w)g=nrho_(B)VgimpliesS.G=(rho_(B))/(rho_(w))=(1)/(n)`
