How is it possible for two neutral objects to become charged by rubbing them together? A. The binding force of the objects’ atom
FinnZ [79.3K]

Answer:

D. The frictional force overcomes the force that binds the electrons to the atoms, enabling the electrons to move elsewhere

Explanation:

Neutral objects becomes charged by rubbing them together due to the frictional force which overcomes the attractive force holding electrons together in an atom.

Friction is the resistance to flow or movement. When we rub bodies together, the movement of electrons becomes inhibited and this can cause an orbital electron loosely held in an atom to be pulled off as the force of friction increases. This mechanism would result in a body losing electron and another readily gaining that electron as they interact. The loss and gain of electrons causes a neutral body to become charged.
