A charged rod extends along the y axis from -2.00 to +2.00 m. The charge distribution on the rod is given by the linear charge density function = 10.0 lyl, all units Sl. The point P is (3.00, 0) m. Calculate: (i) the total charge on the rod, (ii) the potential at P due to the rod, (iii) the electric field at P due to the rod. Do not evaluate any non-zero integrals.
