Gravitation Tes...

The  SI unit of weight is.

If a force of $$10\ N$$ acts on surfaces of areas in the ratio $$1 : 2$$, then the ratio of thrusts is:

A body is lying on the surface of the earth. Suppose that the earth suddenly loses its power of attraction, then:

The apparent weight of a body, weighing M kg-wt, during free fall is

When an object falls freely to the earth, the gravitational force acting on the body

If a force of 10 N acts on two surfaces of areas in the ratio 1 : 2, then the thrust on them has the ratio

A body is thrown vertically upwards and rises to a height of 10 m. The time taken by the body to reach the highest point is :

The force ofgravitation between two bodies of mass 1kg each separated by a distance of 1 m in vacuum is:

The weight of a body would not be zero :

If a rock is brought from the surface of the moon
