| 1 | This is the repulsion, not the repulsion. | |
| 2 | And, there is a mutual repulsive force here. | |
| 3 | Now, how about this repulsion between electrons? | |
| 4 | Therefore, electrostatic repulsion is generally not strong enough to support stable equilibrium beer films. | |
| 5 | And, that's given by the balance between the attractive force of the ions offset by the repulsive force in the electronic shells. |
