1. For each statement select P for Positive, N for Negative, or Z for Zero charge (Neutral). (If the first answer is positive, the second negative, and the third neutral (zero net charge), enter PNZ. Do not enter spaces) A) A negatively charged rod is brought close to a neutral isolated conductor, but it does not touch. The conductor is then grounded while the rod is kept close. If the ground connection is first broken, and THEN the rod is...

Question 1 What is the net electric charge (in units of e) of an atom of lead (Z82)? qlead exact number, no tolerance Attempts: 0 of 5 used Question 2 Suppose a lithium atom (Z units of e? 3) has been singly ionized. What is the net electric charge of the resulting lithium ion in lithium exact number, no tolerance Attempts: 0 of 5 used Question 3 Suppose a lead atom (Z = 82) has been doubly ionized. What is...
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...
