Question

Calculate the force of gravitation between two objects of masses 5o kg and 120kg respectively .kept a distance of 1om from 1 another(g=6.7*nm2

Answer 1

Force between two objects of mass 50kg and 120kg= Gm1m2/r^2 =(6.67×10^-10)(50)(120)/(10)^2 =
6.67×10^-10(6000)/100 =6.67×10^-10(60) =400×10^-10 N=4×10^-8 N(newton).
