## 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
