Question

3. Define gravitational constant G. Write the numerical value of gravitational constant G with its S.I. unit. ​

Answer 1

Answer:

G=6.67×10^-11

S.I unit=Nm^2/kg^2

it's simply the force between two bodies of unit mass separated by unit distance

Answer 2

Answer:

The gravitational constant G is the proportionality constant that is used in the Newton’s Law of Gravitation.

The force of attraction between any two unit masses separated by a unit distance is called universal gravitational constant denoted by G measured in Nm^2/kg^2.

In SI units, G has the value 6.67 × 10^-11 N kg^-2 m^2.

The value of the gravitational constant is the same throughout the universe. The value of G is different from g (the acceleration due to gravity).
