Question

The ratio of earth's gravity to sun's gravity is:
(A) 6
(B) 1/6
(C) 28
(D) 1/28

Answer 1

Hint: We know that gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe. ... where G is called the Gravitational Constant. The gravitational force, as explained by Newton's Law of Gravitation, is inversely proportional to the square of the separation between the two masses (or the separation between the centres of mass for the two objects).

 Complete step by step answer
Gravitational force is given by $\mathrm{F}=\mathrm{Gm}_{1} \mathrm{m}_{2} / \mathrm{r}^{2}$ where $\mathrm{m}_{1}$ and $\mathrm{m}_{2}$ are the masses of the two objects, $r$ is the distance between their centres of gravity, and $\mathrm{G}$ is the universal gravitational constant.
We can say that the gravity on the Sun is 28 times that of the Earth and it can extend out up to two light years away. This indicates that the sun is producing gravity in a similar pattern to light waves. The graviton has an extremely small mass, so small that it can move through space at far distances and return to its original location.
It is a fact that the more mass an object has, the stronger its gravity will be. So given the Sun’s unusually huge mass, it also has an enormous amount of gravity. Here are the facts: the mass of the Sun is 333, 000 times bigger than the Earth’s mass. the mass of the Sun is 1,048 times more than the mass of planet Jupiter.
Thus, we can say that the ratio of earth's gravity to sun's gravity is 1/28.

 Hence the correct answer is option D.

 Note: We can know that about 1.3 million Earths could fit inside the sun. The mass of the sun is $1.989\text{ }\times \text{ }{{10}^{30}}$ kilograms, about 333,000 times the mass of the Earth. Because the Sun continues to 'burn' hydrogen into helium in its core, the core slowly collapses and heats up, causing the outer layers of the Sun to grow larger. It is a very gradual process, and in the last 4 billion years, the Sun has barely grown by perhaps 20 percent at most. The second way the Sun loses mass is through nuclear fusion. The Sun fuses hydrogen into helium in its core, producing its life-giving glow over billions of years. So the Sun loses about 5.5 million tonnes of mass every second, or about 174 trillion tonnes of mass every year.
