Chapter 19, Problem 81GP(choose chapter or problem)
Four lightweight, plastic spheres, labeled A, B, C, and D, are suspended from threads in various combinations, as illustrated in Figure 19–37. It is given that the net charge on sphere D is \(+Q\), and that the other spheres have net charges of \(+Q,-Q, \text { or } 0\). From the results of the four experiments shown in Figure 19–37, and the fact that the spheres have equal masses, determine the net charge of
(a) sphere A,
(b) sphere B, and
(c) sphere C.

Solution 81GP
Step 1 of 4
Here we need to calculate the charges on the three spheres A, B and C, if charge on the fourth sphere D is . It is given that the charges on the three spheres are
,
and
. By using the given figures, we need to calculate the net charge on each sphere.
