ANSWER:
10 eV
STEP-BY-STEP EXPLANATION:
Given:
Carga = 3.2 X 10^-19 C
Voltage = 5 V
Since energy is stored work, we can use the following formula:
[tex]\begin{gathered} V=\frac{W}{q} \\ \\ W=V\cdot q \\ \\ \text{ We replacing } \\ \\ W=5\cdot3.2\cdot\:10^{-19} \\ \\ W=1.6\cdot\:10^{-18}\text{ Joules} \\ \\ 1\text{ eV = 1.6}\cdot\:10^{-19}\text{ Joules} \\ \\ \text{ Therefore:} \\ \\ W=10\text{ eV} \end{gathered}[/tex]The energy required is 10 electronvolts
