How does the Newton’s law relate to the force of gravity

Newton's Law of Gravity says that gravity is a force that acts between any two objects with mass, and that force increases if the mass increases and decreases if the distance between the two objects increases. This force is always attractive, that is, it always works to pull the objects closer together.

Explanation:

I hope this helps

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
