Calculate the force of attraction between the earth and the sun, given that mass of earth is `6xx10^(24)`kg abd mass of sun `=2xx10^(30)`kg. the average distance between the two is `1.5xx10^(11)m.`

Text Solution

Verified by Experts

Here, `m_(1)=6xx10^(24)kg m_(2)=2xx10^(30)kg`
`d=1.5xx10^(11)m F=?`
As `F=(Gm_(1)m_(2))/d^(2)=(6.67xx10^(-11)xx6xx10^(24)xx2xx10^(30))/((1.5xx10^(11))^(2))=3.58xx10^(22)N`
