Question

Relation between universal gravitaional
Constant and the gravitational acceleration on the surface of the earth

Answer 1

Answer:

acceleration due to gravity g=GM/R2(square)

Explanation:

Let g be acceleration due to gravity at a planet of mass M and radius R then by newton's law of motion force F is

F= mass*acceleration due to gravity

OR F=m*g. (3.14)

by newton's gravitational law

F=GMm/R2(square) ( 3.15)

from equations (3.14)and (3.15)

GMm/R2(square)=mg

THEN YOU WILL GET THE ANSWER

Answer 2
