Just use Newton’s equation.
F = (G*M*m)/r^2
By experiment, you can determine the magnitudes of F, M, m, and r.
Now, perform the operation
(M*m)/r^2; and,
compare this to F.
It’s not going to match; ergo, it’s not an equation.
You must introduce a constant; that happens to be G.
That answers why G = .

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
