Physics Question on mechanical properties of fluid

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

A

11+n\frac{1}{1+n}

B

1n\frac{1}{n}

C

n

D

n+1nn+\frac{1}{n}

Answer

1n\frac{1}{n}

Explanation

Solution

Specific gravity = WFn\frac{W}{F_n}
