Question

Choose the correct option

• A. rubber rod becomes positive and fur becomes negative
• B. both rod becomes positive
• C. rubber rod becomes negative and fur becomes positive
• D. both becomes neutral

Answer 1

The correct option is C rubber rod becomes negative and fur becomes positive

On rubbing an rubber rod with fur, the electrons from the fur get transferred to the rubber rod. The fur now has a deficiency of electrons and so is positively-charged. On the other hand, the rubber rod has an excess of electrons and hence is negatively-charged.
In the above example, the fur undergoes positive electrification.It is to be noted that it is the electrons and not the protons that get transferred during positive (and negative) electrification.
