Question

rubbing a comb on hair makes the comb get 0.4 c. find how many electrons are transfered in this process ​

Answer 1

Answer:

2.5× 10¹⁸ electrons are transferred in this process.

Explanation:

As you know that q=± ne

So n= q/e ➜

n= 0.4/1.6×10- ¹⁹ = 0.25 × 10¹⁹ = 2.5 × 10¹⁸

Hence, 2.5× 10¹⁸ electrons are transferred in this process
