Problem 16: A +38 μC point charge is placed 36 cm from an identical +38 μC charge. A -1.5 μC charge is moved from point A to point B as shown in Fig. 17-47. What is the change in potential energy? B 14 cm 12 cm 24 cm FIGURE 17-47 38 μC 38 μC Problem 81. A

(a) How much charge can be placed on a capacitor with air between the plates before it breaks down if the area of each plate is 9.00 cm²? nC (b) Find the maximum charge if nylon is used between the plates instead of air. nC

Given the following system of point charges: a positive point charge +q is placed in the middle, while three negative point charges -q are placed at equal distance from each other and at equal distance R from +q. -9 R +9 -9 Given that q = 13 x 10-9 C and R = 0.6 μm find the work required to construct this system of charges.

How much energy is stored by the electric field between two square plates, 9.1 cm on a side, separated by a 2.3-mm air gap? The charges on the plates are equal and opposite and of magnitude 15 nC.
