Consider a line of length L=0.800 m and uniform positive charge per unit length

Question

Consider a line of length L=0.800 m and uniform positive charge per unit length ?=2.7 ?C. Point A is a distance x=0.19 m from the center of the line, while B is the same distance from the line but a distance y=0.48 m farther along the line; point C is a distance z=0.020 m farther along the line than B. (see figure)

Answer true or false for the following statements. a) The potential at A is higher than the potential at B. b) The potential at B is higher than the potential at C. c) The electric field has a horizontal component at A. d) The electric field has a horizontal component at B. e) The electric field has a vertical component at A. f) The electric field has a vertical component at B. g) If the line were made of a conductor, the charges would re-arrange themselves rather than remaining in this configuration.
