I’m not clear what “atomic scale” means. Nuclei won’t stay together
without nuclear forces. But perhaps that’s “subatomic scale”? So if you’re
saying we’re beyond the scales of the weak + strong forces, but we’re at
the atomic scale where gravity is neglible, then it seems to me the only
fundamental force left is electric. So now I’m wondering whether the
question is some trick of the language because you said “attraction and
repulsion” rather than “the laws of E&M”. If you mean them as synonyms,
then I guess I’ll go with true because they determine phases of matter,
magnetic properties, chemical bonding, and all that. -Carl

Quiz question:
1) ☐ True, or ☐ False: Attraction and repulsion between electric
transformations of matter, as well as the contact forces between material
objects.
2) Explain your answer. How do you know?
