Solution

Image result for Why gravitational constant is the universal constant?

Because universal gravitation constant G is independent of

  • Medium between the two bodies
  • Masses of the two bodies
  • Distance of separation between the two bodies

Its value remains the same in the entire Universe.

The value of G = 6.67 x 10-11 N m2/kg2.




The gravitational constant (also known as the "universal gravitational constant", the "Newtonian constant of gravitation", or the "Cavendish gravitational constant"), denoted by the letter G, is an empirical physical constant involved in the calculation of gravitational effects in Sir Isaac Newton's law of universal.
