Astraight non-conducting line has charges placed on it such that the charge density increases with distance from its center, 0, in both directions, and is given by \lambda = kx2 , where x is measured from 0 and k is a constant. the charged line subtends angle 2\alpha at a point p which is at a distance a from 0. find the electric field intensity at p, in terms of k, a, and \alpha. (note: if you use a variable angle in the integration, do not call it \alpha, which is just a constant)
