From the definition of gravitational constant (G), If the mass of two objects of 1 Kg each is kept at a distance of 1m, the value of gravitational force (F) will become 6.67x10^{-11} N.

By calculation,

Mass of first object (M) = 1Kg

Mass of second object (m) = 1Kg

Distance between them from their center (d) = 1 m

Gravitational Force (F) = ?

We have, gravitational force \(F=\frac{GMm}{d^2}\)

\(=\frac{6.67\times10^{-11}\times1\times1}{1^2}\)

\(=6.67\times10^{-11}N\)
