Alright, so basically you're given: m1+m2=4.0kg, r=25m, Fg=2.5*10-10N
We know that Fg=Gm1m2/r2
Using the fact that m1+m2=4.0kg, we know that m2=4.0kg-m1
So:
Fg=Gm1(4.0kg-m1)/r2
=G(m1(4.0)-m12)/r2
So:
(-G/r2)m12+(4G/r2)m1-Fg=0
Here we can use the quadratic formula to solve for m1
Once you have m1, just use m1+m2=4.0kg to find m2
I'll leave the actual number crunching to you. Hope this helps!
The earth is gravitationally attracted to everything else in the universe, and everything else in the universe is gravitationally attracted to the earth. However, only the nearer objects experience significant mutual attraction.

A star will attract other objects (such as another nearby star, or a planet) gravitationally; in turn, according to Newton's Third Law, it will also be affected gravitationally by the other object. That is, if star "A" attracts star "B", then star "B" will also attract star "A".
The earth is gravitationally attracted to everything else in the universe, and everything else in the universe is gravitationally attracted to the earth. However, only the nearer objects experience significant mutual attraction.
When objects are bound gravitationally in centrifugal motion, the objects are said to be in orbit of each other.
Objects comprise of charges.Opposite charges attract each other.
no,they do not attract.
They do not. Rather, objects with opposite charges attract each other.
