Question 129 of 311

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)

Show answer and solution

Answer: (B)

Using the properties of a dipole and laws of electric field line where two lines should not intersect, the graph would be,
