Question

Explain the transfer of charges in the ebonite rod.

Answer 1

Step 1: Transfer of charges

When we rub two neutral bodies (bodies with no charges), electrons will be transferred from one body to the other. Friction acts on these two bodies that provide the energy which separates the electrons from the atoms. One body receives a negative charge(electrons), while the other receives a positive charge (or the deficiency of electrons), with the magnitude remaining the same in both.

Step 2: Transfer of charges in the ebonite rod

1. The rod is made of vulcanized rubber.
2. When we brush an ebonite rod against a piece of fur cloth, the ebonite rod gains a negative charge, while the fur cloth gains a positive charge.
3. From the fur cloth to the ebonite rod, electrons (-ve charge) are transferred.
