A non-uniform positive line charge of length 2 m is put along the x-axis as shown in the figure, where x,=1.5 m. The linear charge density is given by A(x)=4x C/m. Find the magnitude of the total electric field, E, created by the line charge at the origin using integration. (Take k=9X10N m? /C?) y 1 = 4 x Xo L
