Question

How many electrons can be removed from a piece of metal to give it a positive charge of 10 micro coulomb

Answer 1

Answer:

hlo mate pls mark this answer as a brainliest answer pls pls.

Explanation:

removing each electron will give u 1.603*10^-19 C positive charge. So if u want +1*10^-7 C u need to remove +1*10^-7 / 1.603*10^-19 = 6.2383*10^11 electrons.

hope this helps you. please mark it as brainliest answer.

Answer 2

Answer:6.23×19^11 electrons

Explanation : Q= n ×e

n=Q/e

n= 1×10^-7/1.603×10^-19

n=6.23×10^11 electrons
