Calculate the force of gravitation between the earth and the sun, given that the mass of the earth `=6xx10^(24)kg` and the sun `=2xx10^(10)kg`. The average distance between the two is `1.5xx10^(11)m`.

Text Solution

Verified by Experts

According to question,
M sun = Mass of the sun `=2xx10^(30)kg`
M earth =Mass of the Earth `=6xx10^(24)kg`
R=Average distacne between the earth and the sun `1.5xx10^(11)m`
From universal law of gravitation,
`F=G(Mm)/(R^(2))`
Therefore putting all the value given in question in above equation we get
`((6xx10^(24))xx(2xx10^(30)))/((1.5xx10^(11))^(2))=3.56xx10^(22)N`
