Question

The fur gets positively charged when rubbed with ebonite rod because of deficiency of electrons. The statement is :

• A. true
• B. false
• C. ambiguous
• D. data insufficient

Answer 1

Answer: (A)

true

Answer is A.

When we rub fur with ebonite rod, the chemical bond is formed between some parts of the two surface. Rod has its electron more tightly bound than fur. So, fur donates electrons to the rod while electrons from rod won't come out. Due to excess of electrons in rod, it becomes negatively charged while the fur with lost electrons, becomes deficient of electrons. Thus, fur becomes positively charged.
Hence, the statement is true.
