Question
The figure (a) below shows a circular disk that is uniformly charged. The central z axis is perpendicular to the disk face, with the origin at the disk. The graph (b) gives the magnitude of the electric field along that axis in terms of the maximum magnitude Em (at the disk surface). The z axis scale is set by zs = 8.0 cm. What is the radius of the disk?
The image consists of two parts: a diagram labeled (a) and a graph labeled (b). **Diagram (a):** - This is an illustration of a flat, oval-shaped surface with a vertical arrow labeled "z" passing through it. The shape appears to represent a disc or circular plane oriented perpendicular to the z-axis, indicating the direction of interest or measurement. **Graph (b):** - The graph depicts a curve that shows the relationship between the electric field magnitude (\( E_m \)) and the distance along the z-axis (\( z \)). - The vertical axis represents the electric field magnitude with markings at \( E_m \) and \( 0.5E_m \). - The horizontal axis represents the distance in centimeters (cm), starting from 0 and ending at \( z_s \). - The curve starts at \( E_m \) when \( z = 0 \) and decreases monotonically, approaching a value slightly above \( 0.5E_m \) as \( z \) approaches \( z_s \). - The plot implies an exponential or logarithmic decrease in the electric field magnitude with increasing distance along the z-axis. Major grid lines are present to aid in reading the values. This image could represent a physical scenario where the electric field strength diminishes with distance from a planar source.
