Question

If a charge generator builds a negative static charge of -13.00 mC, how many electrons are transferred to it during this process.

A. 13.0
B. 81.3
C. 2.08×10⁻¹⁸
D. 8.13×10¹³

Answer 1

The number of electrons transferred to the charge generator is approximately 8.13 x 10^16 electrons.

Step-by-step explanation:

In order to determine the number of electrons transferred, we need to use the formula:

Number of electrons = Total charge / Charge per electron

Given that the charge is -13.00 mC (or -13.00 x 10^-3 C), we can convert it to coulombs:

-13.00 mC = -13.00 x 10^-3 C

Now, we know that the charge per electron is -1.6 x 10^-19 C. Plugging in the values:

Number of electrons = -13.00 x 10^-3 C / -1.6 x 10^-19 C

Simplifying the expression:

Number of electrons = 8.125 x 10^16 electrons

Therefore, the answer is approximately 8.13 x 10^16 electrons (option D).
