If a charge generator builds a negative static charge of - 7.00 $\mu { C } \text {, }$ how many electrons are transferred to it during this process. (e = 1.60 × 10^-1⁹ C) A) 4.38 × 10¹³ B) 7.0 C) 1.12 × 10^-18 D) 43.8

Question

Quizplus · Accepted Answer

We know that electrons have a negative charge, so the negative static charge on the generator indicates that electrons have been transferred onto it.

We can use the formula Q = ne, where Q is the charge in coulombs, n is the number of electrons transferred, and e is the charge on each electron.

Substituting the given values, we get: 
-7.00 × 10^-6 C = n × (-1.60 × 10^-19 C)

Solving for n, we get:
n = 4.38 × 10^13

Therefore, 4.38 × 10^13 electrons were transferred to the generator during the process. 
The closest option to this value is A) 4.38 × 10^13, which is the correct answer.
