# Q. 16.     Calculate the force of gravitation between the earth and the Sun, given that the mass of the earth$=6\times 10^{24}kg$ and of the Sun $=2\times 10^{30}kg$   The average distance between the two is  $1.5\times 10^{11}m.$

S Sayak

Mass of the earth, ME $=6\times 10^{24}kg$

Mass of the Sun, MS $=2\times 10^{30}kg$

Distance between the earth and the sun, $d=1.5\times 10^{11}m$

Universal gravitational constant, $G=6.67\times 10^{-11}N\ kg^{-2}\ m^{2}$

The force of gravitation between the earth and the Sun would be given as

$\\F=G\frac{M_{E}M_{E}}{d^{2}}\\ F=6.67\times 10^{-11}\times \frac{6\times 10^{24}\times 2\times 10^{30}}{(1.5\times 10^{11})^{2}}\\ F=3.56\times 10^{22}N$
