[AI-generated answer — Explain Bot]

The equation you have provided is Newton's law of universal gravitation, which describes the force of gravitational attraction between two objects. In this equation, G represents the gravitational constant.

To find the value of G, you can consult various scientific sources or use experimental methods. The accepted value for G is approximately 6.67430 × 10^-11 N(m/kg)^2.

This value was determined through a famous experiment conducted by Henry Cavendish in the late 18th century. Cavendish used a torsion balance, which is a delicate apparatus, to measure the very small gravitational force between two small lead spheres. By comparing the gravitational force to the torsional force, Cavendish was able to calculate the value of G.

Today, the value of G is widely used in various fields of science, including astronomy, astrophysics, and engineering. It enables us to calculate the gravitational forces acting between objects of any mass and distance.
