Although one can electrify a glass rod by rubbing it with silk, no net charge is created.

a. True

b. False

It is true.

As we rub the glass rod with the silk cloth, due to the friction, the electrons are transferred from glass rod to the silk cloth, which makes the glass rod becomes positively charged and silk cloth becomes negatively charged.

The number of electrons lost by the glass rod is equal to the number of electrons gained by the silk cloth, so the net charge is zero.

Answer:True

Explanation:

When we rub a glass rod with silk cloth electrons of glass rod are stripped away by the silk cloth making glass rod Positively charged i. e. relatively glass rod has more positive charge than negative charge.

During this Process no charge is created but transfer of the charges makes the rod relatively Positive and silk cloth relatively negative.

Thus net charge is same and no new charge is created.
