Two particles are placed at some distance. If the mass of each of the two particles is doubled, keeping the distance between them unchanged, the value of gravitational force between them will be

The mass of moon is about 0.012 times that of earth and its diameter is about 0.25 times that of earth .The value of G on the moon will be

 Buoyant force on an object immersed in a liquid acts in upward direction.

Does a sunk body at the bottom of a vessel experience an upthrust?

A spring balance measures the weight of an object in air to be $0.1N$. It shows a reading of $0.08N$ when the object is completely immersed in water. If the value of acceleration due to gravity is $10m/s^2$, the volume of the object is

In what direction does the buoyant force on an object immersed in a liquid act?

What do you mean by buoyancy ?

Imagine a body that is completely submerged in water, but whose depth of submergence can be varied. In which case does it experience a larger upthrust, when it is submergged deep or shallow?

Magnitude of buoyant force depends on __________.
