Question

what happens when two materials are charged by rubbing against each other?
○ both gain electrons.
○ one loses electrons
○ no movement of electron
○ both lose electrons

Explanation:

When two materials are rubbed together, electrons are transferred from one material to the other due to differences in their electronegativities. One material loses electrons (becomes positively - charged) and the other gains electrons (becomes negatively - charged).

Answer:

One loses electrons
