A body of mass $m$ is immersed in water with $3 / 4 t h$ of volume outside of water. Buoyant force acting on it is $1000 N$ . Total volume of body is

( Take density of water as $1000 k g / m^{3}$ and accelaration due to gravity as $10 m / s^{2}$ )

A body is kept on a table. It is pulled downwards due to its weight. But the table exerts an equal and opposite force on the body keeping it at rest.
