An asteroid has acquired a net charge of 105 C from being bombarded by the solar wind over the years,and is currently in equilibrium whereby it expels electrons at the same rate as it acquires them.How many more electrons does it have than protons? A)6.56 × 10²⁰ B)656 C)630 D)1.05 × 10^-17

Question

Quizplus · Accepted Answer

The charge of an electron is approximately -1.6 × 10^-19 C. To find the number of excess electrons, divide the total charge by the charge of one electron: 105 C / 1.6 × 10^-19 C/electron ≈ 6.56 × 10^20 electrons.
