and q=29e? I don't know how to do the rest...

Repulsive force and attractive force? and the repulsive one is slightly larger?

ahh sorry. haven't read the rules yet. I'm sure we can use Coulomb's law. F=KQq/r²

We know that the negative charge on the electron and the positive charge on the proton are equal. Suppose, however, that these magnitudes differ from each other by 0.00007%. With what force would two copper pennies, placed 1.2 m apart, repel each other? Assume that each coin contains 3...
