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 : (figure are schematic and not drawn to scale)

Options

A.
B.
C.
D.

Answer

A

Explanation

Field lines should originate from positive charge and terminate to negative charge. Thus, (B) and (C) are not possible. Electric field lines cannot form corners as shown in (D) Thus, correct option is (A).
