Question

The gravitational force on Earth due to sun is _____ times the gravitational force on Earth due to moon ?​

Answer 1

$\huge\bf\underline\bold\red{AnSwEr}$

Based on its mass, the sun's gravitational attraction to the Earth is more than 177 times greater than that of the moon to the Earth.

Answer 2

Answer:

Earth, Sun and Moon

The average distance between the Earth and sun is 150 trillion meters, or 1.5 x 10^11 meters. The mass of the sun is 1.99 x 10^30 kilograms, while the Earth weighs in at 6.0 x 10^24 kilograms. The gravitational constant is 6.67 x 10^-11 meter^3 / (kilogram - second^2). So the Earth and sun pull on each other with a force equal to 3.52 x 10^22 newtons. The newton is a unit of force equal to a kilogram-meter/second^2. One newton is equal to 0.22 of the rarely used English unit called pound-force, so 3.52 x 10^22 newtons is 7.9 x 10^21 pound-force.

Explanation:

The average distance between the Earth and moon is 380 million meters and the mass of the moon is 7.35 x 10^22 kilograms, so the force between the moon and Earth is 2.03 x 10^20 newtons (4.5 x 10^19 pound-force). That is, the gravitational force between the Earth and moon is about half a percent of the force between the Earth and sun.
