# Worksheet: The Electric Field of a Line of Charge

In this worksheet, we will practice calculating the electric field around a uniform linear charge distribution that is modeled as a set of line segments.

**Q3: **

A long cylinder of aluminum of radius 0.25 meters is charged so that it has a uniform charge per unit length on its surface of C/m. A point is located along a line normal to the cylinder’s axis, 0.15 m from the axis.

What is the magnitude of the electric field at point ?

- A N/m
- B N/m
- C N/m
- D N/m
- E N/m

What is the electric potential at point ?

- A640 kV
- B760 kV
- C830 kV
- D550 kV
- E710 kV

**Q8: **

Two parallel rods of infinite length each carries a uniform charge density as shown in the diagram, in which the rods are seen in cross-section. The distance between the rods .

What is the magnitude of the net electric field from the rods at the point ?

- A N/C
- B N/C
- C N/C
- D N/C
- E N/C

What is the magnitude of the net electric field from the rods at the point ?
