Expert Answer
The question understood is , a charge q is placed at one side of semi-infinite plate .
The charge q is at a distance d from the bottom of the plate.
Electric flux passing through the plate is to be determined.
Let us consider a small area dA at a distance r from bottom edge of plate .
Electric field E due to charge q at this area is given as
where K = 1/ (4πεo ) is Coulomb's constant .
Flux dφ through area is given as , dφ = E dA cosθ
where θ is the angle between electric field direction and norma to the area as shown in figure
Entire flux passing through plate is determined by integrating above expression in r-θ coordinate system
by performing above integration, we get
φ = K × q × π = q / ( 4 εo )
