b Copper (8c25p74) A slab of copper of thickness b = 1.190 mm is thrust into a parallel-plate capacitor of C = 9.0010-11 F of gap d = 5.0 mm, as shown in the figure; it is centered exactly halfway between the plates. What is the capacitance after the slab is introduced? Submit Answer If a charge q = Tries 0/4 3.00106 C is maintained on the plates, what is the ratio of the stored energy before to that after the slab is inserted? Submit Answer Tries 0/4 How much work is done on the slab as it is inserted? Submit Answer Tries 0/4 Is the slab pulled in or must it be pushed in? pulled pushed Submit Answer Tries 0/4
