Question

Solid will sink in a liquid if its density is ________ than the density of the liquid. (lower/greater)

Answer 1

1. For a body to float in water, the weight of the body in the downward direction must be equal to the buoyant force exerted on the body in an upward direction.
2. The more the density of a body, the more is its weight and vice versa.
3. More the density of a liquid, the more buoyant force it exerts on a body and vice versa.
4. When the density of a body is greater than the density of the liquid, the weight of the body exceeds the buoyant force and the body sinks.

Hence, a solid will sink in a liquid if its density is greater than the density of the liquid.
