===== - The electrostatic self-repulsion force between 1-μm lunar dust particles at -100V is about 10−1810^{-18}10−18 N. =====
* This force is much weaker than lunar gravity for 1-μm grains, so large grains won’t levitate.
* However, submicron grains (0.1 μm and smaller) can experience forces comparable to or greater than their weight, supporting the idea of electrostatic dust lofting on the Moon.

Would you like calculations for different dust sizes or conditions (e.g., -500V charging in Earth's magnetotail)?
