Could i please get some help with this, it would mean a lot, thank you.

Question 1 You build a parallel plate capacitor from two 4.00 cm diameter aluminum disks and 0.300 mm rubber spacers. You then connect your capacitor to a 56.0 V battery; after the capacitor is fully charged, how much charge is on the positive electrode? 0 0.257 nC C 2.57 n0 0 5.29 n0 0 2.08 nC Question 2 C1 + C2 C3 What is the equivalent value of the capacitance for the figure shown? C, = 14.0 UF, C2= 21.0 HF and C3 = 17.0 pF. O 0.178 UF O 10.2 UF O 52.0 UF O 5.62 UF Question 3 A uniform electric field exists within a region that is 4.80 cm x 4.80 cm x 4.80 cm in size. If the energy stored within the field is 3.80x10-17 J, what is the magnitude of the electric field? O 279 V/m O 31.3 V/m O 188 V/m 963 V/m
