If two objects are close to each other and the mass of one object decreases, what happens to the force of gravity acting between the objects?
1. it decreases
2. it stays the same
3. it increases
4. It increases or decreases, depending on how much the mass increases

anonymous · Answer

Newtonian gravitation is very similar to Coulomb's law. Here it is:

$$F=G\frac{m_{1}m_{2}}{r^{2}}$$

So, consider what happens when you lower m1 or m2. The force will decrease.
