Relation between buoyant force and the volume of an object immersed in liquid is:

What is the relationship between buoyant force and the weight of liquid displaced?

If relative density of a substance in $$0.8$$, is it heavier or lighter than water?

How much of the iceberg has a weight equal to the buoyant force? 

An apple falls from a tree because of gravitation between the earth and apple. If $$F_1$$ is the magnitude of force exerted by the earth on the apple and $$F_2$$ is the magnitude of force exerted by apple on earth, then

A planet whose mass and radius are both half of that of earth. Acceleration due to gravity(g) at its surface should be:

Two thin circular discs of radii $$3 cm$$ and $$4 cm$$ respectively are placed separately at the bottom of a vessel containing water. The ratio of thrusts, acting on them will be:

Pick up the correct relationship

Which of the following statements about weight is/are false ?
$$1$$. Weight does not change when location changes.
$$2$$. Weight is a force.
$$3$$. Weight is measured in kilograms.
$$4$$. Weight is proportional to the amount of gravity acting on an object.

Any solid will not sink in water if its relative density is
