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? :)
