Question

If 31.25

Answer 1

Answer:

it will become charged by Q = 5C

Explanation:

When electron is removed from matter then the system will get positively charged

So we will have

$Q = Ne$

here N = number of electrons that is removed

$N = 31.25 \times 10^{18}$

also we know that charge on one electron is given as

$e = 1.6 \times 10^{-19}$

here we have

$Q = Ne$

$Q = (31.25 \times 10^{18})(1.6 \times 10^{-19})$

$Q = 5 C$

so it will become charged by Q = 5C

Answer 2

1 C = 6.24150965(16)×10^18 electrons

31.25 x 10^18 electrons / (6.24150965(16)×10^18 electrons / C) = 5.007 Coulombs

I hope this helps.
