A very long solid cylinder of radius R = 4 cm has a uniform volume charge density ?
a.) How much total charge is contained on a 1 m length of this cylinder?
b.) What would be the effective linear charge density along the length of this cylinder?
c.) For a given length of cylinder, what percentage of its total charge lies between 0 and R/2?
d.) Outside: What is the electric field at a radial distance of 5 cm from the axis of the cylinder?
e.) Inside: What is the electric field at a radial distance of 3 cm from the axis of the cylinder?
