Charge on balloon = \(- 10^{-14}C\) Thus, as it is negatively charged, we know that it has an excess of electrons. 1 electron charge = \(-1.6 * 10^{-19} C\) Thus if one electron has \(-1.6 * 10^{-19} C\) charge. Then let x electrons have \(- 10^{-14}C\) charge. Therefore, more electrons means more charge thus they have a direct relation. Thus,\[\frac{x}{1} = \frac{- 10^{-14}C}{-1.6 * 10^{-19} C}\] \[x = 62500\] And therefore we can conclude, that the number of extra electrons on the ballon = 62500\(e\) Understood? :)
