Write properties of Gravitational Constant (G).
Answers
Explanation:
Cavendish experiment
…of the value of the gravitational constant, G. 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.
In Newton's law, it is the proportionality constant connecting the gravitational force between two bodies with the product of their masses and the inverse square of their distance.

Values of G Units
6.67430(15)×10−11 m3⋅kg–1⋅s–2
4.30091(25)×10−3 pc⋅M⊙–1⋅(km/s)2
The constant, G, determines the strength of Newton's inverse square law in a particular system of physical units and is, not surprisingly, known as Newton's constant of gravitation. It is considered to be a fundamental constant of nature.In SI units, G has the value 6.67 × 10-11 Newtons kg-2 m2. The direction of the force is in a straight line between the two bodies and is attractive. Thus, an apple falls from a tree because it feels the gravitational force of the Earth and is therefore subject to “gravity”.Value of G is about 6.67408 ×10−11 SI unit of G is m3 kg-1 s-2 or N*m2/kg2. • G refers to gravitational constant.
