Two persons having mass \(50\ kg\) each, are standing such that their centre of gravities are \(1\ m\) apart. Calculate the force of gravitation between them. (Take \(G\ =\ 6.67 \times 10^{−11}\ Nm^2kg^{−2}\), Mass of earth \(M\ =\ 6 \times 10^{24}\ kg\), Radius of earth \(R\ =\ 6.4 \times 10^6\ m\))
