Question

Describe an simple experiment to show that total charge on a pair of objects that have been rubbed together is zero.

​

Answer 1

• An electrically charged object can attract objects that are uncharged.

• When a glass rod is rubbed against a silk cloth, then glass object acquires positive charge and silk cloth acquired negative charge.

• The amount of charge acquired by both the object must be equal, so that the net charge of the system is zero.

• This is so because, according to the law of conservation of charges, charge can neither be created nor can it be destroyed

Answer 2

Explanation:

WHEN WE TAKE TWO OBJECTS.. A glass rod and a silkmoth , a glass rod is rubbed against a silk cloth, then glass object shows +ve charge and silk cloth acquired -ve charge. The amount of charge acquired by both the object must be equal, so that the net charge of the system is zero
