Coulombs law

• Why Does Gravity Hold the Planets in Orbit if Electric Forces Are Stronger?
  Electric forces between particles can dwarf gravity, but stars and planets are nearly neutral; their mass adds up, so gravity governs their orbits.
• How Are Coulomb’s Law and Electric Field Intensity Related?
  Coulomb’s law gives the force between charges; electric field intensity is the force per unit positive test charge at a point.
