QUESTION 11 A parallel plate capacitor has capacitance C when the area of each plate is A the separation between plates is d, and the medium between plates is the vacuum. What will be the new capacitance when the separation between plates is doubled 2d and a dielectric with constant 2 is filling the space between the plates? C-C C-20 C-4C C-
