PRACTICE IT Use the worked example above to help you solve this problem. A parallel-plate capacitor has an area A = 1.90 x 10-4 m2 and a plate separation d = 1.10 x 10-3 m. (a) Find its capacitance. F (b) How much charge is on the positive plate if the capacitor is connected to a 3.00 V battery? с (c) Calculate the charge density on the positive plate, assuming the density is uniform. C/m2 (d) Calculate the magnitude of the electric field between the plates. V/m EXERCISE HINTS: GETTING STARTED I'M STUCK! Two plates, each of area 3.20 x 10-4 m2, are used to construct a parallel-plate capacitor with capacitance 1.50 pF. (a) Find the necessary separation distance. d = m (b) If the positive plate is to hold a charge of 5.30 x 10-12 C, find the charge density. C/m2 o = (c) Find the electric field between the plates. E = N/C (d) What voltage battery should be attached to the plate to obtain the preceding results? V= V
