First Long Exam Second Semester, AY 2016–2017 Physics 72 11.Predicted Winner sa Miss U.A thin spherical vacuum-filled insulating shell, with radiusRand charge-Q, is centered at the origin. It is placed in between the infinite rod andinfinite plane, each with uniform charged density+λ0and+σ0respectively. The infiniteplane is parallel with theyz-plane, and the infinite rod lies on thexy-plane as shown in thefigure. What is theelectric fieldat P(+R/2,0)? 12. X-Factor.The cross-sections of three infinite conducting cylindrical shells, together withtheir radii, are shown in the figure. The charge densities in the three conductors are uni-formly distributed over their bodies. The figure is not drawn to scale. What is theelectricfieldatr= 4R? A – 7
