Question

(iii) The value of ‘g’ keeps changing as we move away from the earth whereas value of ‘G’ remains constant all over the universe.

Answer 1

G is the universal constant. it does not change with respect to position or distance.
g is acc. due to force of gravity which is dependant on distance between the objects.

Answer 2

G is the universal gravitational constant

g is the acceleration due to gravity.

Explanation:

The Universal gravitational constant(G) can be defined as the gravitational force between two bodies of unit mass which is separated by a unit distance. It is constant and universal.

Whereas, (g) acceleration due to gravity can be defined when a body freely falls under the effect of gravity by a constant acceleration.

It is not constant it varies depending upon the rotation, depth  and altitude.
