What is the charge of a metal ball if N = 4.0 * 10 excess electrons on it?
September 21, 2021 | education
| The given problems: N (the number of excess electrons on the taken metal ball) = 4 * 10 ^ 10 electrons.
Reference values: e (electron charge) = -1.6 * 10 ^ -19 Cl.
The charge of the taken metal ball is determined by the formula: q = N * e.
Let’s calculate: q = 4 * 10 ^ 10 * (-1.6 * 10 ^ -19) = -6.4 * 10 ^ -9 Cl = -6.4 nC.
Answer: The charge of the taken metal ball is -6.4 nC.
