Question

Is value of ‘G’ same everywhere

Answer 1

Answer:

Gravity is assumed to be same everywhere, on earth, but it varies because the planet is not perfectly spherical or uniformly dense. The value of G is 6.67 × 10^11 Nm^2/ kg^2. It is constant everywhere because is it is standard value termed as ( universal gravitational constant).

Answer 2

Answer:

Value of G is universally constant which is 6.67 x 10^(-11) N m^2/ kg^2.

Explanation:

I'll explain about both g and G.

g = acceleration due to gravity

Value of g varies. g value depends upon the distance from the centre of earth. Earth is not perfectly spherical. It is a common notion that value of g is constant but in actuality it is taken as constant to reduce the complexity of problem.

Value of g is weaker at equator due to centrifugal forces produced by earth's rotation. In short as we move away from earth's centre value of g reduces.

Now coming onto G.

G= universal gravitational constant

G value does not change. If you want a detailed version which involve the understanding of inverse density and other parameters do let me know.
