Sketch the electric field lines for a uniformly charged hollow cylinder shown in the figure.

Electric field lines originate from positive charges and extend radially outward. For a uniformly charged hollow cylinder,the field lines are perpendicular to the surface of the cylinder. In the radial direction (perpendicular to the axis),the field lines point outward. Near the ends of the cylinder,the field lines curve outward,reflecting the non-uniformity of the field at the edges. This is illustrated in the provided figure.
