a.) Find the surface charge density of the disk.

b.) At the point on the central axis perpendicular to the disk, 10.0 cm away from the center of the disk, the magnitude of the electric field is measured 1.00×105 N/C. Estimate the total charge of the disk.

c.) Find the magnitude of the electric field due to this disk at the point on the central axis, 1.00 cm away from the center.

d.) Find the magnitude of the electric field due to this disk at the point on the central axis, 2.00 cm away from the center.

e.) Find the magnitude of the electric field due to this disk at the point on the central axis, 5.00 cm away from the center.

f.) Find the magnitude of the electric field due to this disk at the point on the central axis, 8.00 cm away from the center.

g.) Find the magnitude of the electric field due to this disk at the point on the central axis, 15.0 cm away from the center.

h.) Make the graph of the magnitude of the electric field due to this charged disk on the central axis for the distance from 0 to 20 cm. Add marks for the electric field calculated in c), d), e), f) and g).
