As a result: charged A) 3.00 x 10' N/C B) 6.00 x 10' N/C C) 9.00 x 10' N/C D) 1.20 x 10° N/C E) 1.80 x 10 N/C F) 2.40 x 10° N/C OO A) both spheres are neutral B) both spheres are positive C) both spheres are negative D) the left sphere is negative and the right sphere is positive E) the left sphere is positive and the right sphere is negative insulating supports 20. A conducting shell has an inner radius R0.2 m and an outer radius R... - 0.25 m respectively. A solid conducting sphere of radius Rhere 0.1 m is located inside the shell at its center. The sphere contains a charge of 3.0 µC and the shell contains a net charge of 6.0 µC. What is the magnitude of the electric field 0.3 m from the center of the solid sphere? B) 2.4 x 10¹ J C) 3.6 x 10 J D) 4.8 x 10 J. E) 6.0 x 10 J F) 7.2 x 10 J 21. A parallel-plate capacitor has a capacitance of 2.8 µF. The capacitor is connected to a 12-volt battery. Then, the battery is disconnected and the spacing between the capacitor plates is decreased by a factor of 2. The energy is stored in the capacitor is most nearly A) 1.8 x 10-J
19. Two uncharged metal spheres, shown below, are in contact. A negatively charged rod is brought- close to the left sphere, but does not contact it, as shown. The rod is withdrawn and then the two spheres are separated. As a result: charged insulating supports A) both spheres are neutral B) both spheres are positive both spheres are negative D) the left sphere is negative and the right sphere is positive Ey the left sphere is positive and the right sphere is negative be here to search 20 A conducting shell has an inner radoss R-0,2 m and an outer radius R-0.25 m respectively. A solid conducting sphere of t 0.1 m is located inside the shell at uts center. The sphere contains a charge of 3.0 µC and the shell contains a net charge of 60 pc What is the magnitude of the electric field 0.3 m from the center of t solid sphere? TE
