4. A parallel plate capacitor consists of two 1.2cm by 1.2cmplates which are .5mm apart. The capacitor is attached to a 2Vbattery (with no other circuit components.) (a) What is thecapacitance of the capacitor? (b) What is the voltage across it?(c) What is the magnitude of charge on each plate? (d) What is themagnitude of the electric field between the plates? (e) How muchenergy is stored in the capacitor? (f) The battery is disconnectedfrom the capacitor, and a dielectric is placed between the plateswith a dielectric constant κ = 5.25. Now recalculate all of thequantities asked for in (a)-(e).
