An infinite sheet of charge that has a surface charge density of 23.4 nC/m^2 lies in the yz plane at x=0. A long wire having a linear charge density of 84.2 nC/m lies parallel to the y axis and intersects the x axis at x = 3.34m. The potential at the origin is 1.41 kV. Determine the potential on the x axis at x=0.832m, between wire and sheet. Part b) what is the potential energy of a 1.86 nC charge placed at x= 0.832m
