Question

The number of electrons in 2C of chare is

a] 1.6x10-9 b] 3.2x10-19 c] 1.25x1018 d] 12.5x1018​

Answer 1

Answer: d) 12.5*10^18

Explanation:

apply q=n e where

q is total charge that is 2C (given)

n= no. of e-

e = charge on 1 e- i.e. 1.6*10^-19

2=n*1.6*10^-19

n=2/1.6*10^-19

n=1.25*10^19=12.5*10^18

with best wishes
