If all matter were made of electrically neutral particles such as neutrons, then will all of the following be correct:

  1. there would be no force of friction
  2. there would be no tension in the string
  3. it would not be possible to sit on a chair
Yes No

As we know Friction is an electromagnetic force .It arises due to attraction in opp charges hence if all the particles are neutral there would be no friction. Same is the case with chair and string .They would not exist.Smithreens of atoms scattered everywhere.

Seems to be an awesome view if u imagine.

The next question to ask is, "If there were no electrically neutral particles, will all the following be correct:", followed by the same list. The first thing is since photons have no charge there would be no photons, and hence no way to see what was happening, (which raises the question, "what would happen if photons had a charge? Must a particle have mass in order to have a charge?"). Neutrinos would not exist, nor would many of the short-lived "exotic" particles, but the big issue would be if neutrons did not exist; how much does it matter that neutrons have no charge? What would happen if all neutrons suddenly became protons?

Everything would became unstable coz of unbalance -ve and +ve charges.Charge neutrality of earth would be destroyed and there will be reconfiguration of every matter and everything would collapse.In short ,APOCALYPSE.

Haha. Yeah, bad things would probably happen, but it's still an interesting question to think about. :)

If a body possess a charge it will certainly have mass and vice versa.

Do a moving photon has a charge?But remember it has mass.

Hence vice versa isn't true as i think..Are you charged or is the earth. And charge implies mass is true till day but the main reason is that no of diff massless particles are very less(only three or two coz there is ambiguity about gravitons)

@Gautam Sharma – It is not theoretically impossible for a particle without mass to have charge, (at least in some models). So while photons have neither mass nor charge, I just thought it was interesting to speculate on what would happen if photons, or some other massless particle, did have charge. We don't really know what "charge" is fundamentally; we know that it is a property of matter and can observe its effects, (and without it everything would fall apart), but our understanding of the nature of charge is still a work in progress.

@Gautam Sharma – For vice versa i meant, if a body possess pass that is due to atoms and mass of atom is due to e − e^ {- } and p p , n n , and they are charges.

Although we haven't found any massless charged particles yet, it is still theoretically possible that they exist, (at least in some models).
