What is the separation D between the plates in mm?




A parallel plate capacitor has an area of A = 11.4 cm2 and a capacitance C = 55.9 pF. What is the separation D between the plates in mm?







The full question states, A parallel plate capacitor is connected to a battery. If we double the plate separation,

1. the capacitance is doubled
2. None of these
3. the charge on each plate is halved
4. the potential difference is halved
5. the Electric field is doubled
