Question

how manY electron are there in a charge of -1.6×10^-6 milli coulomb​

Answer 1

Answer:

10^10

Explanation:

10^-6-3/10^-19 = 10^10

Answer 2

There are $10^{10}$ electrons.

Explanation:

Charge,

$q=-1.6\times 10^{-6}\ mC\\\\q=1.6\times 10^{-9}\ C$

We need to find the number of electrons. It can be calculated using the concept of quantization of charge as :

q = ne

n is number of electrons

$n=\dfrac{q}{e}\\\\n=\dfrac{-1.6\times 10^{-9}}{1.6\times 10^{-19}}\\\\n=10^{10}$

So, there are $10^{10}$ electrons.
