11. (a) The vertical components of the individual fields (due to the two charges) cancel, by symmetry. Using d = 3.00 m and y = 4.00 m, the horizontal components (both pointing to the x direction) add to give a magnitude ofEx ,net = 2|q|d 2(8.99 109 N m

17. We make the assumption that bead 2 is in the lower half of the circle, partly because it would be awkward for bead 1 to slide through bead 2 if it were in the path of bead 1 (which is the upper half of the circle) and partly to eliminate a second solu

21. Think of the quadrupole as composed of two dipoles, each with dipole moment of magnitude p = qd. The moments point in opposite directions and produce fields in opposite directions at points on the quadrupole axis. Consider the point P on the axis, a d

23. We use Eq. 22-3, assuming both charges are positive. At P, we haveEleft ring = Eright ring 4 0 ( R + R2q1 R2 3/ 2)=q2 (2 R) 4 0 [(2 R ) 2 + R 2 ]3/ 2Simplifying, we obtainq1 2 = 2 q2 53/ 2 0.506.

25. From symmetry, we see that the net field at P is twice the field caused by the upper semicircular charge + q = R (and that it points downward). Adapting the steps leading to Eq. 22-21, we findj Enet = 2 () sin 4 0 R9090 q j. = 2 2 0 R (a) With

30. (a) It is clear from symmetry (also from Eq. 22-16) that the field vanishes at the center. (b) The result (E = 0) for points infinitely far away can be reasoned directly from Eq. 2216 (it goes as 1/z as z ) or by recalling the starting point of its de

31. First, we need a formula for the field due to the arc. We use the notation for the charge density, = Q/L. Sample Problem 22-3 illustrates the simplest approach to circular arc field problems. Following the steps leading to Eq. 22-21, we see that the g

36. We write Eq. 22-26 as E z = 1 2 Emax ( z + R 2 )1/ 2 and note that this ratio is 2 (according to the graph shown in the figure) when z = 4.0 cm. Solving this for R we obtain R = z 3 = 6.9 cm.1
