Question

Find the gravitational force between the sun and the earth.The mass of the sun is 2.0×10000000000000000000000000000000000000kg and that of the earth 6.0×1000000000000000000000000kg.The distance between sun and earth is 1.5× 100000000000m

Answer 1

Mass of Sun = 2.0×10000000000000000000000000000000000000 kg
= 2 * 10^37 kg

Mass of Earth = 6.0×1000000000000000000000000 kg
= 6.0 * 10^24 kg

Distance between Sun from Earth = 1.5* 100000000000 m
= 1.5 * 10^11 m

F = GMm / r^2
= (6.6 * 10^-11 * 2 * 10^37 * 6 * 10^24) / (1.5 * 10^11)^2
= 3.52 * 10^29 N

You should learn how to write numbers in scientific terms.
