When two objects are rubbed together, there is a transfer of electrons. What seems to be the important variable in determining which object acquires the transferred electrons?

• The relative size of the two objects

• The relative roughness of the two objects

• The relative affinity that each object has for electrons.

• The number of electrons initially possessed by each object.
