Question

define universal gravitational constant​

Answer 1

Answer:

The force of gravitation between two unit masses separated by unit length is called universal gravitational constant.

F = G m1 × m2 / r^2

Here masses are 1 unit and r is 1 unit

So,

F = G.

Answer 2

Answer:

The gravitational constant, denoted by the letter G, is an empirical physical constant involved in the calculation of gravitational effects in Sir Isaac Newton's law of universal gravitation and in Albert Einstein's general theory of relativity
