What are the interatomic forces keep atoms seperated, and how much force (in Newtons) do they produce?

Electronic repulsion.
Go look at a lennard-jones potential.

Three problems

1. I have no idea what they're talking about
2. I can't do that math and,
3. It doesn't say a specific force in newtons

>> No.1174745

The force between two objects from charge is based on distance and charge of the two objects, so it really depends on which specific thing you're looking at

restate

How much force would it take to pull two particles together so they were 1x10^-25 m apart?

read this page:

use equation at bottom.

sure is homework thread in here

As long as the particles are of the same charge they should repel each other naturally.
