What will be the formula for the mass of the Earth in terms of $g$,$R$,and $G$?

Weight of a body is maximum at

Identify the incorrect statement. The acceleration due to gravity $g$ decreases if:

If the earth rotates faster than its present speed,the weight of an object will

If $M$ is the mass of the Earth and $R$ is its radius,the ratio of the gravitational acceleration $g$ to the gravitational constant $G$ is:

The acceleration due to gravity on the planet $A$ is $9$ times the acceleration due to gravity on planet $B$. $A$ man jumps to a height of $2 \ m$ on the surface of $A$. What is the height of jump by the same person on the planet $B$?
