When a Certain Capacitor Carries Charges of ±10 µC on Its

When a certain capacitor carries charges of ±10 µC on its plates,the potential difference cross the plates is 25 V.Which of the following statements about this capacitor are true? (There could be more than one correct choice. )

A) If we double the charges on the plates to ±20 µC,the capacitance of the capacitor will also double.
B) If we double the charges on the plates to ±20 µC,the potential difference across the plates will also double.
C) If we double the charges on the plates to ±20 µC,the capacitance of the capacitor will not change.
D) If we double the charges on the plates to ±20 µC,the potential difference across the plates will decrease by a factor of two.
