Question

How, if at all, would the physical universe be different if protons were negatively charged and electrons were positively charged?

Atoms would consist of protons orbiting a nucleus composed of electrons and neutrons.

Like charges would attract, and opposite charges would repel. Since protons are more massive, the universe would acquire a net negative charge.

The value of the Coulomb constant k would change.

Gravity would be a repulsive force instead of an attractive one.

There would be no difference other than the sign on the charged particles.

Explanation / Answer

The positive and negative charges assigned to protons and electrons respectively are by convention.

SO correct statement is -->>There would be no difference other than the sign on the charged particles.
