Q. A circular disc of radius 𝑅 carries surface charge density

σ (r) = σ_{o} (1 - \frac{r}{R})

σ_{o}

is a constant and

r

is the distance from the center of the disc. Electric flux through a large spherical surface that encloses the charged disc completely is

. Electric flux through another spherical surface of radius

\frac{R}{4}

and concentric with the disc is

ϕ

.Then the ratio

\frac{ϕ_{0}}{ϕ}
