A point charge Q is placed at the vertex of a cone with height 12 cm and radius 5 cm. Then electric flux through the curved surface of the cone is

• A

  $\frac{\mathrm{Q}}{5{\mathrm{\epsilon }}_0}$

• B

  $\frac{\mathrm{Q}}{13{\mathrm{\epsilon }}_0}$

• C

  $\frac{\mathrm{Q}}{18{\mathrm{\epsilon }}_0}$

• D

  Zero
