Simply the Gravitational Force
None. Change your question for two OBJECTS and the answer is friction.
Electric Force is the force between charged objects.
The mass of the two objects and the distance between them control the force of gravity between them. The equation for the force of gravity between two objects is Fg=(GMm)/R2, so if two objects are very massive, the force will be greater, and if two objects are very close the force will be greater. The force of gravity is directly related to the mass of the objects and inversely related to the distance between them.the earth
The force that pulls objects into a circular path is called CENTRIPETAL FORCE.
If the objects are the same distance apart (center to center), then the gravitational force between two less massive objects will be less than the gravitational force between two more massive objects.
The easiest to observe would probably be gravity, just drop something!
As first observed by Isaac newton, gravitational force is directly proportional to mass.
directly proportional because force=(mass)(acceleration) (f=ma)
Absolutely ALL objects does this. Large objects, much force. Small objects, little force. Black holes, Humoungus force.

Electric Force is the force between charged objects.
When an objects net force is zero, its acceleration is zero. No force , no acceleration.
Objects acccelerate when a force is applied, a=F/m.
Wich force?
Force of gravity on objects m and M is mGM/r2.
The mass of the two objects and the distance between them control the force of gravity between them. The equation for the force of gravity between two objects is Fg=(GMm)/R2, so if two objects are very massive, the force will be greater, and if two objects are very close the force will be greater. The force of gravity is directly related to the mass of the objects and inversely related to the distance between them.the earth
Macro objects can attract through gravitational or electromagnetic force. Repulsion can be observed only for later ones. Nature of gravitational force is not understood yet. But electromagnetic attraction is due to certain magnetic, or/and static or/and electric charge.
