**The Charge on an Object - Examples**- **A balloon rubbed against someone’s hair gains nine electrons. What is the charge of the balloon in coulombs?** - **Proportion?** \[ \frac{1e}{1.6 \times 10^{-19}C} = \frac{9e}{x} \]In the equation provided, the proportion is used to determine the charge of nine electrons when given the charge of a single electron. The left side of the proportion represents the charge of one electron (1e) divided by the fundamental charge of an electron in coulombs (\(1.6 \times 10^{-19}C\)). The right side of the equation sets this equal to the charge of nine electrons (9e) divided by the unknown charge (x) in coulombs.To solve for x (the total charge), you would cross-multiply and solve:\[1e \times x = 9e \times 1.6 \times 10^{-19}C\]\[x = 9e \times 1.6 \times 10^{-19}C\]\[x = 1.44 \times 10^{-18}C\]Thus, the charge of the balloon after gaining nine electrons is \(1.44 \times 10^{-18}\) coulombs.
