Calculate the force of gravitation between the earth and the sun, given that the mass of the erath `=6 xx 10^(24)kg` and of the Sun `=2 xx 10^(30)kg`. The average distance between the two is `1.5 xx 10^(11)m`.

Answer

The force of gravitation between the earth and the sun is `3.56 xx 10^(22)N`

Explanation

Here, `M_e=6 xx 10^(24)kg,`
`M_s=2 xx 10^(30)kg, d=1.5 xx 10^(11)m`.
`F=G (M_em_s)/(d^2)`
`=(6.67 xx 10^(-11) xx 6 xx 10^(24) xx 2 xx 10^(30))/((1.5 xx 10^(11)^(2)) N`
`=(6.67 xx 12xx 10^(43))/(2.25 xx 10^(22)) approx 3.56 xx 10^(22)N`
