Ans. We know the charge on an Electron is {tex}1.6 \times 10^{-19} C{/tex}
So e = {tex}1.6 \times 10^{-19} C{/tex}
Total Charge Required q = 2 C
Since , q = ne
where n is no of electrons.
So, n = {tex}q\over e{/tex} = {tex}2\over 1.6 \times 10^{-19} {/tex}
= {tex}{2 \times 10^{19} \over 1.6 }{/tex} = {tex}1.25 \times 10^{19}{/tex}
