D 2. If a parallel plate capacitcr has the positive plate charged to +0. What is the charge at the minus plate? 3. A parallel plate capacitor has a charge of 1 x 10"C and potential of 1 V. What is the electric potential energy of the capacitor? 5 x 10-7 J 5 x 10 8 J O 5 x 104 J 5 x 106 J5. A parallel plate capacitor has a separation distance of 2 mm and an area of 100 mm. What is the capacitance? (80 = 8.85 x 10-12 c2/Nm?) O 4.4 x 107 F O 8.8E x 10-10 F O 50 F 4.4 x 10-13 Fm a. Moving a small positive test charge closer to a positive source charge requires: 0 a negative electric field D 7. A parallel plate capacitor has a set area but can change the distance between the plates. It you double distance between the plates} you would expect the capacitance to change by a factor of
