The value of the gravitational constant at any part of the universe remains constant which is 6.67408 × 10-11 N m2 kg-2.

What is the Universal Law of Gravitation? Newton's Law of Universal Gravitation states that every particle attracts every other particle in the universe with force directly proportional to the product of the masses and inversely proportional to the square of the distance between them.

In SI units, its value is approximately 6.674×10−11 N⋅m2/kg2. The modern notation of Newton's law involving G was introduced in the 1890s by C. V. Boys.

The acceleration due to gravity on Earth or the value of g on Earth is 9.8 m/s2. This implies that, on Earth, the velocity of an object under free fall will increase by 9.8 every second. This acceleration is due to the Earth's gravity.

In Newton's law of universal gravitation, the attractive force between two objects (F) is equal to G times the product of their masses (m1m2) divided by the square of the distance between them (r2); that is, F = Gm1m2/r2. The value of G is (6.6743 ± 0.00015) × 10−11 m3 kg−1 s−2.

So we have theMoreAnd if mass 1 is M. And mass 2 is 3 times the size of mass 1 and we'll call it 3m. So we have the names now of our masses that's one we'll call em mass. - we'll call 3m.

F = Gm1m2 / r2 Gravitational Force = (Gravitational Constant × Mass of first object × Mass of the second object) / (Distance between the centre of two bodies)2.
