Aline of charge lies along the x-axis extending from x- 0mto x- 3 m. the line charge density is a function of the distance from the coordinate beginning x and is given byn- 2 x [nc/m]. 1. find the total charge of the line charge q 2. using coulombs law calculate the electric field on the x-axis at: x 6m and at x = 250 m. 3. find the field at x-250 m, assuming that you have a point charge at x-0 whose charge is the same as the total charge q of the line charge compare the result with the value calculated under (b). comment on the difference between the two values
