Attractive force
The force acting among the objects that tends to closer together is attractive force. The opposite concept of attractive force is repulsive force. Repulsive force tends the particle to go away as far as possible. within an electrostatic force there exist both attractive force and repulsive force. Centripetal force tends to electron to go to nucleus and centrifugal force tends electron far away from the nucleus. Within a magnet we find that opposite pole of magnet attract each other and same pole of magnet repulse each other. Same electric charge repulse each other and opposite electric charge attract each other.
