Hi,

 

The cause for the appearence of charge q on the plates of a capacitor is the applied Voltage.

Thus, greater the applied voltage, greater is the charge that will appear on the Capacitor.

Hence we take q proportional to V

 

A proportional to B

is same as saying

B is proportional to A

 

All that matters is the linear Relationship between the two physical quantities.

 

Regards,

Rajat
