Using the diagram shown A) find the torque between the 2 objects (length and mass were...
8. Find the location X on the x-axis (other than infinity) where the electric field goes to zero. a) Use little test arrows representing the two electric fields to determine if X lies to the left of q1, to the right of q2, or in between. Is the location of X likely to be closer to qi or q2? Place an X at a location on the x-axis satisfying the two concepts above. b) Sketch a distance, x, to represent...
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...
