Detailed Solution

Concept: The formula provided by Newton, which determines the strength of this attraction force between any two objects, will be utilized to answer this question, which is just based on the gravitational force of attraction.
This force between any two bodies is given by mathematics.

When the gravitational constant G is used .

The weight of a single body,

is a different body's mass.
Additionally, we know from the theory of mathematics that we must differentiate the equation in order to obtain the maximum or lowest value of any value.
As a result, this query has: M is the previous body's mass.
m - a bodily part that has broken,

- is the second body's mass.
Due to the fact that the gravitational attraction between two things is caused by

We must differentiate the aforementioned equation and then equate it to zero in order to get the maximum.

Thus, the greatest force between them occurs when.

Hence, the correct option is 2.
