A metallic object holds a charge of −2.9 × 10−⁵ C.What total number of electrons does this represent? (e = 1.6 × 10−¹⁹ C is the magnitude of the electronic charge. ) A) 1.8 × 10¹⁴ B) 2.4 × 10¹³ C) 6.1 × 10¹³ D) 4.2 × 10¹⁴

Question

Quizplus · Accepted Answer

The total number of electrons is equal to the charge on the object divided by the charge of a single electron. So, the number of electrons is:```n = Q / e = (-2.9 × 10^-5 C) / (1.6 × 10^-19 C) = 1.8 × 10^14 electrons```
