8.5 Electric Flux
IntermediateMCQMathematical22.6k
A flat ellipse viewed at a 3D perspective tilt represents a circular disk of radius R lying in a horizontal plane. A vertical dashed central axis line passes perpendicularly through the center of the disk. A single point charge labeled q is positioned on this vertical axis at a perpendicular distance d directly above the center of the disk. A radial arrow labeled R extends from the center of the disk to its right edge. A vertical arrow labeled d extends along the central axis from the center of the disk up to the point charge q. No other labels, lines, text, or axes appear.
Point charge \(q\) located a distance \(d\) above the center of a circular disk of radius \(R\).
A point charge \(q\) is fixed on the central symmetry axis of a flat, circular disk of radius \(R\) at a perpendicular distance \(d\) from the center of the disk. Which of the following expressions represents the net electric flux through the disk?
