Answer 1

G= 6.673 x 10-11 m3s2/kg

It is Universal law of gravitation because anywhere in the Universe same value og G is required to calculate the gravitational force

Answer 2

The SI unit of G is 6.67×10-11 kg-1 m3s-2.

Its value remains constant at anywhere in the universe this is the reason it is a universal constant. Its existence comes as proportionalityconstant.
