An insulator has a positive electric charge of 8 × 10 -17 C. How many electrons were added or removed?

Question

Quizplus · Accepted Answer

The insulator has a positive charge, indicating electrons were removed. The charge of one electron is approximately 1.6 × 10^-19 C. The total charge is 8 × 10^-17 C. To find the number of electrons, divide the total charge by the charge of one electron: (8 × 10^-17 C) / (1.6 × 10^-19 C/electron) = 500 electrons. Therefore, 500 electrons were removed.
