Question

Calculate the charge carried by 4*10 to the power 20 electrons

Answer 1

Answer:

-64 coulombs.

Explanation:

We know,

The charge of a single electron is -1.6 x 10^ -19 Coulomb.

So, charge of 4×10^20 electrons = {-1.6×10^-19 × 4×10^20}coulombs.

Now, the value after the calculation is -6.4×10^(-19+20)

= -6.4×10

= -64coulombs
