Homework Statement



A single infinitely conductor with a diameter of 10mm and a height of 3m above ground is charged to a voltage of 20kV above earth
a. Find the charge/meter on the conductor.
b. Find the capacitance/meter on the conductor.

Homework Equations



I don't know if these are right but to find the capacitance I used C=4(pi)(epsilon)(r)
To find the charge per meter I used charge/meter=(pi*epsilon)/ln(d/a)
where d=height and a=radius.

The Attempt at a Solution



a. Charge/meter=4.876x10-12
b. C=5.563x10-13
