CE Four lightweight, plastic spheres, labeled $A, B, C,$ and $D,$ are suspended from threads in various combinations, as illustrated in FlGURE $19-47 .$ It is given that the net charge on sphere $D$ is $+Q$ , and that the other spheres have net charges of $+Q,-Q,$ or $0 .$ From the results of the four experiments shown in Figure $19-47,$ and the fact that the spheres have equal masses, determine the net charge of (a) sphere $A,(b)$ sphere $B,$ and $(c)$ sphere $C$ .
Four lightweight, plastic spheres, labeled A, B, C, and D, are suspended from threads in various combinations, as illustrated in Figure 19.24. The total charge on sphere $D$ is $+Q$, and the other spheres have a total charge of $+Q,-Q$, or 0 . From the results of the four experiments shown and the fact that the spheres have equal masses, determine the total charge of (a) sphere $A$, (b) sphere $B$, and (c) sphere $\mathrm{C}$.
Four identical metal spheres have charges of $q_{\mathrm{A}}=-8.0 \mu \mathrm{C}$ $q_{\mathrm{B}}=-2.0 \mu \mathrm{C}, q_{C}=+5.0 \mu \mathrm{C},$ and $q_{\mathrm{D}}=+12.0 \mu \mathrm{C}$ (a) Two of the spheres are brought together so they touch, and then they are separated. spheres are brought together so they touch, and then they are separated. Which spheres are they, if the final charge on each one is $+5.0 \mu \mathrm{C} ?$ (b) In a similar manncr, which three spheres are brought together and then separated, if the final charge on each of the three is $+3.0 \mu \mathrm{C} ?$ (c) The final charge on each of the three separated spheres in part (b) is $+3.0 \mu \mathrm{C}$ . How many clectrons would have to be addcd to onc of these spheres to make it electrically neutral?
