Answer:
6.48*10⁻⁷ C
Explanation:
- By definition, the capacitance of a capacitor is expressed as follows:
- where Q is the charge on one of the plates of the capacitor, and V the potential difference between the plates.
- The maximum electric field, the potential difference, and the distance between plates are related by the following expression:
- Replacing by the givens, we can find V as follows:
- Now, we can find the maximum charge Qmax, as follows:
- The maximum charge that the capacitor can hold is 6.48*10⁻⁷ C.
