Question

When two objects are rubbed against each other they______ .

• A. will loose electrons
• B. will repel electrons
• C. will attracts each other
• D. may attract or repel each other

Answer 1

The correct option is C will attracts each other

Answer is C.

Different materials have different amounts of attraction for electrons. When two objects rub against each other it is likely that one will steal electrons from the other. Objects may become charged in many ways, including by contact with or being rubbed by other objects. This means that they can gain or lose negative charge. For example, when we rub our feet against the carpet, negative charge is transferred to us from the carpet. The carpet will then become positively charged by the same amount. Now, unlike charges attract each other.
