Question #869fd

Answer 1

No.

Theoretically it may be fine to do so. But not experimentally as Gravitation is a weak interaction. Moreover, proposed values of mass and distance are empirical in nature.

Explanation:

As per Law of Universal Gravitation the force of attraction between two bodies is directly proportional to the product of masses of the two bodies. it is also inversely proportional to the square of the distance between the two. That is the force of gravity follows inverse square law.
Mathematically

`F_G prop M_1.M_2`
Also `F_G prop 1/r^2`
Combining the two we obtain the proportionality expression

`F_G prop (M_1.M_2)/r^2`
Follows that

`F_G =G (M_1.M_2)/r^2`

Where `G` is the proportionality constant.
It has the value `6.67408 xx 10^-11 m^3 kg^-1 s^-2`

It would be extremely difficult to measure Gravitational constant with accuracy on the basis of suggested definition.

Moreover, we need to standardize various physical constants.
Proposed mass of `5kg` and distance of `5m` are empirical values and certainly not standard values.
