HW2 due on 1/24
(1) Using the Coulombs law directly, calculate the electric field of an infinitely long
1D charge (uniformly charged wire). The line charge density is L. P.39.
(2) Using the Coulombs law directly, calculate the electric field of an infinit
HW3 due on 1/31
In all answers, clearly indicate the coordinate system.
(1) Using Gausss law, calculate the electric field (magnitude and direction) of an
infinitely long 1D charge (uniformly charged wire). Choose a cylinder as the
Gauss geometry. P.62,63
HW4 due on 2/7
The general procedure is obvious. First, give +Q and Q to capacitor metals. Then,
calculate the E-field using Gausss law and calculate voltage. C is given by Q/V.

I am adding subjects randomly chosen.
- The field directions are a , a , az, aR, etc. depending on if it is the E/H field and the
symmetry of the charge/current. Can you write
