1. For the x, y, and z components of the electric field over this region. What is the magnitude of the field at the point P, which has coordinates (in meters) (1, 0, -2)?
2. Two capacitors C1 and C2 (where C1 > C2) are charged to the same potential difference V0, but with opposite polarity. The charged capacitors are removed from the battery, and their plates are connected as shown in Figure 26.10a. The switches S1 and S2 are then closed as in Figure 26.10b.
(a) Find the final potential difference between a and b after the switches are closed.
(b) Find the total energy stored in the capacitors before and after the switches are dosed. direction of the electric field, E, and the direction of the positive x axis at the point P, which has coordinates (in meters) (1, 0, 1).
