Question

Rank the average gravitational forces from greatest to least between (a) the Sun and Mars, (b) the Sun and the Moon, and (c) the Sun and Earth. Rank from greatest to least. To rank items as equivalent, overlap them.

Answer 1

Answer:

b,c,a.

Explanation:

We know that mass of sun > mass of Earth> mass of mars>mass of mars.  

And Gravitation force F =$\frac{GmM}{r^2}$

G= gravitational constant

m= mass of lighter body

M= mass of heavier body.

r= distance between them.

Although the mass of earth is greater than that of moon , its distance from the sun is larger hence, gravitational force on moon by sun is greater than that on Earth.

Hence the correct order will be

b,c,a.
