Question

Find the charge if number of electron is 4 x 10-18

Answer 1

Answer:

0.64 C

Explanation:

n = 4 x 10^-18

e = 1.6 x 10^-19

As we know,

charge (Q) = No. of electrons ( n) x charge in one electron ( e)

Q = ne

= 4 x 10 ^ -18 x 1.6 x 10^ -19

= 0.64 C

Answer 2

The charge on is $q=6.4\times 10^{-37}\ C$.

Explanation:

Number of electron is, $n=4\times 10^{-18}$

Let q is charge. It is given by the quantisation of electric charge. It is given by :

$q=ne$

e is the charge on electron

$q=4\times 10^{-18}\times 1.6\times 10^{-19}$

$q=6.4\times 10^{-37}\ C$

So, the charge on is $q=6.4\times 10^{-37}\ C$. Hence, this is the required solution.
