A parallel plate capacitor has capacitance (Co). C, where 'd' is the separation distance between the plates. There exists a minimum plate separation (s) to keep the capacitor from discharging. Thus, Cp the electrometer is connected to the capacitor, the system capacitance becomes (Co+CP) Adding charge to the system produces an electrometer reading VE- ,-E07-_ where 'x' represents any additional plate separation. When QIf Cris changed Co+CP) to Cp' by changing the plate separation, the electrometer changes: V- Co+Cp Q3:...
