Question

state and explain newtons law of gravitation.establish the relation between g andG​

Answer 1

G stands for Newton's universal gravitational constant, whereas g stands for the acceleration due to gravity at a certain point. ... (According to Newton's law of universal gravitation the force of attraction between two bodies is given by F = GMm/r 2, where the symbols stand for their usual well known meanings.

or

G is the force between two bodies of unit mass separated by a unit distance is known as universal gravitational constant. Whereas, g is the acceleration produced in a body falling freely under the action of gravitational pull of the Earth is known as acceleration due to gravity or g.
