About 20 pounds at sea level.
When friction is createed between two objects, the objects create static electricity! :D
friction
Friction is caused by the interlockings that are present between the two bodies in contact due to the irregularities of the surfaces. Greater the interlocking greater is the friction.
1:the tongue and the teeth. 2:the piston in an engine, and the cylinder: there is minor friction there, so to lessen the friction even more, oil is added
The distance, and the amount of charge on each object.

Static Friction
that is friction

The masses of the objects and the distance between them.
The friction between 2 objects makes them squeak

Static and Kinetic friction, static is the friction between two objects when they are not moving (relative to each other) an example of this is and object staying still on a sloped surface. obviously, kinetic friction is the friction between two objects that are moving and making contact, for example wind resistance.
Friction between two objects depends on the static coefficient of friction (if the object is currently not moving) and the normal force from the surface, acting in the direction opposite the direction of gravity.
The 2 masses and the distance between them.
The distance, and the amount of charge on each object.
