Two bodies each of mass 10 kg attract each other with a force of 0.1 milligram weight. What is the distance between them ?

Explanation

Here, `m_(1)=10 kg,m_(2)=10kg.`
`F=0.1` milligram `wt.=10^(-7) kg wt=9.8xx10^(-7)N`
`d=?`
From `F=(Gm_(1)m_(2))/(d^(2))`
`d^(2)=(Gm_(1)m^(2))/(F)=(6.67xx10^(-11)xx10xx10)/(9.8xx10^(-7))=6.81xx10^(-3)`
`d=sqrt(68.1xx10^(-4)) =8.25xx10^(-2)m=8.25cm`.
