A circular disk with radius \( R \) has a constant surface charge density, \( \sigma \).a) Determine the electric potential, \( V(z) \), a distance \( z \) directly above the center of the disk.b) From this potential, determine the magnitude of the electric field, \( |\vec{E}(z)| \), a distance \( z \) directly above the center of the disk.c) Verify that your answer in part b) gives the correct result in the two extreme cases: 1) very close to the charged disk (\( z \ll R \)), and 2) very far away from the disk (\( z \gg R \)).**Diagram Explanation:**The diagram illustrates a circular disk viewed from above, with radius \( R \). A line is drawn vertically (dashed) from the center of the disk, representing the distance \( z \) directly above the disk's center to a point. The concepts above relate to calculating the electric potential and field due to a surface charge on the disk, with focus on different distances from the surface.
