Question

Calculate the force of gravitation between two objects of masses 80 kg and 1200 kg kept at a distance of 10m from eachother Given, `G=6.7xx10^(11)Nm^(2)//kg^(2)`.

Answer 1

Correct Answer - `6.40 xx 10(-8)N`
Here, `m_(1)80kg,m_(2)=1200kg, r=10m, G=6.67xx10^(-11)Nm^(2)//kg^(2), F=?`
Thus, `F=(Gm_(1)m_(2))/r^(2)=(6.67xx10^(-11)xx80xx1200)/(10)^(2)=6.40xx10^(-8)N`
