Question

calculate the force of gravitation due to a woman of 60 kg on her child 25 kg standing at a distance of 1 m from her.

G = 6.7 x 10^-11 Nm²/kg²

Answer 1

Details of the question is as below:

Mass of woman, Mw	60 kg
Mass of child, Mc	25 kg
Distance between child and the woman, r	1 m

The gravitational force between woman and the child,
$F=\frac{G{M}_w{M}_c}{r^2}=\frac{6.67\times {10}^{-11}\times 60\times 25}{1^2}=10005\times {10}^{-11}=1.0005\times {10}^{-7}\text{N}$
