Question

what charge is acquired by a glass rod and silk when silk cloth is rubbed on glass rod​

Answer 1

Answer:

When glass rod is rubbed with silk, electrons move from rod to silk.

Since silk gets electrons it becomes negatively charged and the number of electrons gained by silk is same as that lost by rod.

Hence magnitude of charge on silk is same as that on rod.

Hence charge on silk=−1.6×10

−11

C

Answer-(D)

Answer 2

Answer:

When the glass rod is rubbed with silk clothes, glass quickly loses electrons, and silk takes electrons out of the glass rod. So after rubbing, the glass rod becomes positively charged and the silk gets negative charge.
