Diagnostic Test 6

Consider the given diagram. If $V_1=4 V$, each plate of the capacitor has surface area $100 cm^2$, and the plates at 1mm apart, determine the excess charge on the positive plate.

A capacitor is placed in series with a 6Vbattery. The plates are 1mm apart and each have a $4cm^2$ surface area. Determine the charge on the positive plate.
