Answer 2

Answer:

Or, G = [M1 L1 T-2] × [L]2 × [M]-2 = [M-1 L3 T-2]. Therefore, the gravitational constant is dimensionally represented as M-1 L3 T-2.

What is the numerical value of G and its SI unit?

In SI units, G has the value 6.67 × 10-11 Newtons kg-2 m2.

What is G in Newton's law of universal gravitation?

The gravitational constant is the proportionality constant used in Newton's Law of Universal Gravitation, and is commonly denoted by G. This is different from g, which denotes the acceleration due to gravity. In most texts, we see it expressed as: G = 6.673×10-11 N m2 kg-2.
