Question

_________ electrification is due to the deficiency of electrons.

• A. Negative
• B. Positive
• C. Nuetral
• D. None of the above

Answer 1

The correct option is B Positive

Negative electrification is due to the excess of electrons (compared to the normal number of electrons in a neutral atom).
For example, on rubbing a glass rod with silk, the electrons from the glass rod get transferred to the silk. The silk now has an excess of electrons and so is negatively-charged. On the other hand, the glass rod is deficient in electrons and hence is positively-charged.
In the above example, the silk undergoes negative electrification.
Hence, negative electrification is due to the excess of electrons.
