Particles of the same charge repel eachother
A force that acts between particles with opposite chargesAPEX
Two particles of the same charge will experience an electrostatic repulsive force. Specifically, the force is given by Coulomb's Law.
Assuming that the only force on the two objects is an electric force. Felectric = k Q q / r2 This is Coulomb's law. K = electrostatic constant, Q and q are the magnitudes of the point charges, and r is the distance between the point charges. As you can see, if you decrease the magnitude of the charge, the electric force decreases. In other words, the objects are less attracted to one another. aside: gravity happens to be modeled the same way.
No. Both forces obey an inverse-square law, so the ratio of electric to gravitational force will always be the same, for the same pair of particles - no matter the distance.No. Both forces obey an inverse-square law, so the ratio of electric to gravitational force will always be the same, for the same pair of particles - no matter the distance.No. Both forces obey an inverse-square law, so the ratio of electric to gravitational force will always be the same, for the same pair of particles - no matter the distance.No. Both forces obey an inverse-square law, so the ratio of electric to gravitational force will always be the same, for the same pair of particles - no matter the distance.

Yes. They stand for the same
Yes, electrostatic force obeys Newton's third law; equal and opposite. Example 1: the electrostatic force on a single Na+ due to a single Cl- in a crystal of NaCl is the same magnitude but opposite in direction. Example 2: the electrostatic force on a single Na+ due to a single SO4^2- in a solution of Na2SO4 is the same magnitude as the force on the SO4^2- but in the opposite direction.

The numbers will be the same, because electric field is defined as "force per unit charge". The units, however, will not be the same.
Reactive centrifugal force is not the same thing as centrifugal force. Reactive centrifugal force is the reaction force. It is the reaction force reacting to a centripetal force.
A different factor. If you increase the distance by a factor of 10, the force decreases by a factor of 100, which is 10 squared. The same rule applies both to gravitational and to electrostatic forces.

An electric field has what are called lines of force that radiate outward from the electric charge that creates them. It is the "touch" or the interaction with these lines of force that allow an electric field to exert a force (an electrostatic force) on anything with an electric charge.A fundamental law of electrostatics is that like charges repel and opposite charges attract. A charge will have an electric field around it, and if another charge is nearby, the fields of the charges will interact. Like charges will "push" on each other, while opposite charges will "pull" on each other. It's the fields of the respective charges that interact to cause the effects we see.All electric charges have associated electric fields around them. It is possible to "see" the electric fields like we "see" gravimetric fields. Both forces can "reach across" space to interact with objects at a distance from the source of the force. The field lines (lines of force) carry the force outward and are the means by which interaction occurs.
