Use the following information to answer the next question.
During an experiment, Mukhtar rubs a plastic comb against his dry hair and then brings the comb near some paper pieces. The paper pieces get attracted toward the comb.
During this experiment,
charging by both friction and induction occur
When an object is charged by rubbing it, the process is called charging by friction. Mukhtar rubs the comb against his dry hair. Hence, the comb becomes charged by the friction between the comb and the hair.
When a charged object is brought near an uncharged object, the uncharged object becomes charged with the opposite charge. Since unlike charges attract each other, these two objects attract each other. This is called charging by induction. Hence, when Mukhtar brings the charged comb near the paper pieces, they become charged and get attracted toward the comb. Therefore, during the given experiment, charging by both friction and induction occur.
