The SI unit of thrust is

If the symbols have their usual meanings then $$\dfrac {gR^2}{M}$$ represents.

Any solid will float in water if its relative density is :

If the density of a metal is 8.2 g/cc, its relative density is.

The gravitational attraction between the two bodies increases when their masses are

A force of 50 N is applied on a nail of area 0.001 sq cm. Then the thrust on the nail is equal to

Any solid will sink in water, if its relative density is :

The total force exerted by a body perpendicular to a surface is called.

The upward force acting on the body immersed in a fluid is called :

A force of 50 N is applied on a nail of area $$0.001\ cm^2$$. Then the thrust applied is:
