Question

A charge is kept at the central point P of a cylindrical region. The two edges subtend a half-angle $\theta$ at P, as shown in the figure. When $\theta = 30$ , then the electric flux through the curved surface of the cylinder is $Φ$. If $\theta= 60\degree$ , then the electric flux through the curved surface becomes $Φ/√𝑛$, where the value of n is______.
