Question

Derivation of Gravitational constant
Please tell me the derivation I shall be thankful for the answerer.

Answer 1

Answer:

According to Newton's Law of Gravitation,

            F ∝ m1×m2  (where m1 and m2 are masses of the body)

               ∝ 1/r²

      ∴F∝m1×m2/r²

        F=G×m1×m2/r²

              where G is called gravitational constant.

Rearranging it we get,

                   G=F×r²/m1×m2

This is the expression
