Consider a horizontal charged disk with center \(O\) and having surface charge density \(\sigma\), and radius \(R\), Consider a vertical rectangle of dimensions \(2a \times 2h\), which cuts the disk at a distance \(a\) from its center, such that half of rectangle lies below the disk and half of it lies above the disk.Use \(a << R\) to find the value of flux of electric field in \( N m^2 C^{-1} \) through the rectangle to the nearest integer. The top view is shown below:
Details and assumptions
\(\sigma = 1.05 \times 10^{-4} Cm^{-2}\)
\( R = 3m \)
\( a = 2 mm\)
\( h = 1m\)
