Can someone show how to solve it pl

According to the law of universal gravitation, which is a classical physical law that describes the gravitational interaction between different bodies with mass:

Where:

is the module of the force exerted between both bodies

is the universal gravitation constant.

and are the masses of both bodies.

is the distance between both bodies

In this case we have a gravitation force , given by the formula written at the beginning. Let’s rename the distance as :

    (1)

And we are asked to find the gravitation force with a given distance of :

    (2)

The gravity constant is the same for both equations, and we are assuming both masses are constants, as well. So, let’s isolate in both equations:

From (1):

    (3)

From (2):

    (4)

If (3)=(4):

    (5)

Now we have to find :

    (6)

If :

>>>>This is the new force of attraction     

it is the second option.

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
