) An air-filled parallel plate capacitor has plates of area 9.5 cm² separated by a gap of 1.6 mm.A potential difference of 25.0 V is applied to the plates. Calculate

i. the electric field between the plates, ii. the surface charge density on the plates, iii. the charge on each plate, iv. the capacitance. (b) Six identical capacitors, each of capacitance C, are connected in the network shown in the figure. What is the effective capacitance of the combination?
