S.I. Unit of universal gravitational constant $$G$$ is-

If the radius of the earth shrinks by $$1.5$$% (mass remaining same), then the value of acceleration due to gravity changes by :

Variation of acceleration due to gravity $$\left(g\right)$$ with distance $$x$$ from the centre of the earth is best represented by : ($$R \rightarrow$$ Radius of the earth)

At the centre of the earth acceleration due to gravity is:

Dimensional formula of universal gravitational constant $$G$$ is-

The minimum speed of a particle projected from earth's surface so that it will never return is/are:

A particle hanging from a massless spring stretches it by $$2\ cm$$ at earth's surface. How much will the same particle stretch the spring at height $$2624\ km$$ from the surface of earth? ( Radius of earth $$=6400\ km$$)

The SI unit of gravitational potential is

How the gravitational constant will change if a brass plate is introduced between two bodies?

The minimum energy required to launch a $$m$$ kg satellite from earth's surface in a circular orbit at an altitude of $$2R$$ where $$R$$ is the radius of earth, will be:
