For a physics lab on the Triboelectric effect, we rubbed two rods with fur which gave both of them a positive charge.
We then brought them close together, and they obviously repelled. We then held one rod down firmly and touched the rods together. We were able to do so.
Coulomb's Law says that as the distance between two like charges become zero, the force becomes infinite. Using superposition on all the charges in the rod, shouldn't the infinite force have prevented us from touching the rods together?
