JEE MAIN - Physics (2015 (Offline) - No. 14)
A long cylindrical shell carries positives surfaces change $$\sigma $$ 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 :

Paliwanag
From the property of electric filled lines we know,
Electric filled lines stars from positive charge and ends at negative charge.
As density of cylinder is uniform so all the lines comes out of positive charge should enter to the negative charge.
From this discussion we can say (C) is correct.
