The G is represented as “Universal Gravitational constant” in the gravitational force equation acting between the two objects.
Explanation:
The force of gravitation is given by following equation,
![\bold{F= (- G (M m))/(r^2)}](https://img.qammunity.org/2020/formulas/physics/middle-school/5825qdqhdzk6y2yepthy0279wwu46mrbkd.png)
F - Force of gravitation,
G - Universal gravitational constant,
M - Mass of
object,
m - Mass of
object,
R - Distance between two objects.
The negative sign here denotes that gravitational force is experienced along the line of separation of the two objects. And it also indicates that it is an attractive force between the two.
