5. PROBLEM # 37 (page 524) a. Sketch the electric field lines around an isolated point charge q < O. b. Sketch the electric field pattern around an isolated negative point charge of magnitude -2q. 6. PROBLEM #51 (page 525) Four closed surfaces Sl through S4 together with the charges -2Q and Q, are sketched in Figure P 15.51. ( The colored lines are the intersections of the surfaces with the page). Find the electric flux through each surface. Figure P15.51
