An ionized hydrogen atom is created in a vacuum exactly in the center between two horizontal (in the xy plane) parallel disks one mm apart (along the z axis). An electrical potential of 50 volts is applied to the top disk while the bottom disk is held at zero volts.
• What is the electric field at the position of the ionized particle (Hint: remember the result of the two parallel lines you plotted – or use Gauss’s Law to derive the field). Sketch the electrical equal-potential lines between the disks in the xz plane at the center of the disks (PLEASE INCLUDE THIS SKETCH)
• If the ion is initially traveling at velocity +vo horizontally along the x axis, where does it go? Write the equation of motion for the particle and make a sketch of its trajectory. Can you ignore the force of gravity?

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
