The weak and strong nuclear forces are really the same force. All forces are equally effective over all ranges. None of the fundamental forces have been proven to exist. The electrical force is the same as the gravitational force.19. If a charge is not on a field line, it feels no force.
Field lines are real.
Coulomb's law applies to charge systems consisting of something other than point charges. A charged body has only one type of charge. The electric field and force are the same thing and in the same direction. There are a finite number of field lines. Fields don't exist unless there is something to detect them.
