A long cylindrical shell carries positive surface charge $\sigma$ in the upper half and negative surface charge $-\sigma$ in the lower half. The electric field lines around the cylinder will look like figure given in : (figures are schematic and not drawn to scale)

(JEE MAIN-2015)

Solution

Field lines originate perpendicualr from positive charge and terminate perpendicular at negative charge. Further this system can be treated as an electric dipole.
