If the spacing between the plates, d, is the same in both capacitors, and the voltage across capacitor 1 is v, what is the voltage across capacitor 2?

Capacitance is proportional to Area/
distance (A)
We also know Q = V*C (B)
1) from (A) we know capacitance of
capacitor2 is twice that of capacitor 1,
and from (B) we know voltage is
inversly proportional to capacitance
so voltage across capacitor2 is V/2
