Answer
When the charge on a capacitor doubles, the capacitance of the capacitor does not change.
Work Step by Step
The capacitance of a capacitor depends on physical properties of the capacitor such as area, separation distance, or radius if the capacitor is spherical. Therefore, changing the charge on a capacitor does not change the capacitance.
