Calculate the force between two masses of 50 kg and 100 kg separated by a distance of 10 m.
3.335×10−9 N
According to Newton's law of gravitation, force of attraction between two bodies is
F=Gm1m2r2
Here, m1=100 kg, m2=50 kg
r=10 m,G=6.67×10−11 Nm2kg2
⇒F=6.67×10−11×100×50102
=33.35×10−10 N
=3.335×10−9 N
