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

When a body slides down from rest along a smooth inclined plane making an angle of $45^?$ with the horizontal, it takes time $T$. When the same body slides down from rest along a rough inclined plane making the same angle and through the same distance, it is seen to take time $pT$, where $p$ is some number greater than $1$. The co-efficient of friction between the body and the rough plane is
