Two stars, star 1 and star 2 are at almost equal distances from earth

Star 1- 3.61 mass of star
Star 2- 3.59 mass of star

Which stamens is correct
A-Earth exerts almost equal gravitational force on both stars
B-earth exerts more gravitational force on star 1
C-star 1 attracts star2 with greater gravitational force than star 1
D-star 2 attracts star 1 with a greater gravitational force than star 1 attracts star 2

A) is the answer.

B) looks fine, because M1 > M2, but we don;t know the actual distance with precision. Only approximately.

C and D) no sense, gravitational force of 1 upon 2 is the *same* as 2 upon 1 For instance: apple and Moon.

Answer:

Option B and C

Step-by-step explanation:

The mass of star 1 is greater than star 2 and hence the gravitational force exerted by star 1 on star 2 is greater as compared to the gravitational force exerted by star 2 on star 1

As per the standard equation - gravitational force between two objects is equal to


= (g* m_1* m_2)/(r^2)

This equation clearly states that the gravitational force exerted between any two objects is governed by the masses of these objects.

Thus, earth (with constant weight ) exerts more force on star1.
