Hello,I've got the correct answer for #2 but gravity is negative in this situation and I can't square root a negative number. I still get the correct answer if I change it to a positive number.

What is the best answer regarding what's true about the gravitational force? It has the unit of Newtons. It acts on both masses as a Newton's 3rd Law pair. It decreases with distance like an inverse square law. All the answers are correct.
Some of the most spectacular objects in the universe are fairly small: neutron stars are spheres with a diameter that'sabout 10km (they are remnants of old stars). Their spectacular nature is indicated by the fact that they are about asmassive as the sun, i.e. 2 x 1030kg. What is the gravitational acceleration on the surface of such an object? Expressyour result as a multiple of g.

Let's say that I want gravitational force Fg = 1.00 N. what combination of m1, m2, and r will give that? Hints: There are many possible answers, you just need to find one. To avoid trial and error, you can pick values for m2 and r (distance) then use Newton’s law of gravity to find the m1 value giving Fg = 1 N.
