EM -86 Charge 5. A thin semicircular rod like the one in problem 4 is broken into two halves. The top half has a total charge + Q uniformly distributed along it, and the bottom half has a total charge -Q uniformly distributed along it. On the diagram, indicate the direction of the net electric force on a positive test charge placed in turn at points A, B, and C. Explain how you determined your answers. 6. A positive point charge +q is placed near an uncharged metal rod. Sketch the charge distribution on the rod. b. Is there a non-zero net electric force on the rod? Explain. a. +q A C. Is there a non-zero net electric force on the point charge? Explain. +Q B с :) Uncharged metal rod
