Question

what is the force of gravitation between the earth and the sun given that the mass of sun is 2×10^30kg.mass of earth is 6×10^24.the average distance between them is 1.5×10^11m​

Answer 1

Explanation:

the force of gravitation between the earth and the sun given that the mass of sun is 2×10^30kg.mass of earth is 6×10^24.the average distance between them is 1.5×10^11m

Answer 2

Given :

$M_1$ =mass of sun=$2×{10}^{30}\:kg$

$M_2$=mass of earth=$6×{10}^{24}\:kg$

R= Avg. distance between the Earth and the Sun $=1.5×{10}^{11}\:m$

$G=6.7×{10}^{-11}\:N{m}^{2}/{kg}^{2}$

According to universal law of gravitation,

$\begin{gathered}F=\frac{G×M_1×M_2}{{r}^{2}}\\\\=\frac{6.7×{10}^{-11}×2×{10}^{30}×6×{10}^{24}}{{(1.5×{10}^{11})}^{2}}\\\\\\\underline{F=3.57×{10}^{22}\:N}\\\\\\\underline{\boxed{\sf{ F=3.57×{10}^{22}\:N}}} \end{gathered}$
