Answer 1

Answer:

If the value of "g" is doubled, then what will be the value of "G"? Will it be doubled or remain same?

Let we see relation of g and G

Fgrav=Gm1m2R2

In other form, Fgrav=m1g

… so we get value of g as function:

Gm1m2R2=m1g

g=Gm2R2

Your question: If the value of "g" is doubled, then what will be the value of "G"? Will it be doubled or remain same?

First, remember that G was constant whose value is fixed (by research and experiment). So, if there is condition that the value of g is doubled, the value of G is not doubled (it is fixed), but value of m2 (see equation above) must be doubled or you must change the value of R to get double g .

Value of G is still the same.

Answer:

if R is doubled what will be the change in equation g=GMe/R2
