Question

In a system of 2 large round objects, R1 and R2 (R1 is larger), what properties will affect the force of gravity between them? (select all that apply)

Answer 1

According to Newton's Law of Universal Gravitation, if two particles with masses M and m are located a distance r from each other, an attractive force between them appears, and its magnitude is given by:

`F=G(Mm)/(r^2)`

Where G is the gravitational constant:

From the equation, we can see that the properties that affect the force between them are their masses and the distance between them.

Then, the correct choices are:

- Mass of R1

- Mass of R2

- Distance from the center of R1 to the center of R2.
