Gravity.
law of attraction
electric force
Specific gravity is the ratio of a substance's density to that of a standard, usually water. Gravity is a force of attraction between two bodies. We usually think of the gravitational force of the earth as the force of attraction for bodies on the surface of the earth, but all objects exert a tiny attraction for each other.
Gravitational Forces
The possible interactions between two charged objects are: law of repulsion: when two objects have the same charge they repel each other because the force of attraction is weaker Law of Attraction: When two objects have two different charges they attract each other because the force of attraction is stronger.
law of attraction
Electrostatic attraction or repulsion, magnetic attraction or repulsion, gravitational attraction.

That would be "Gravity".
Gravitational Forces
i think its the centripetal force [force of attraction]
This is technically not true. All forms of mass exert gravitational attraction on one another. However, since the Earth is billions of times more massive than most objects, the gravitational force of the Earth is commonly seen. The gravitational force between a stapler and a computer monitor is not large enough to make the two objects fly across a room to get to one another. However, both do exert a gravitational attraction on one another.
