On this page I will post the problems discussed in workshop, and their solutions. All problem numbers from Griffiths refer to the 4th edition of the textbook.

  • Week of Sept 4 - review vector algebra and gradients

    Griffiths Example 1.2
    Griffiths Problem 1.5
    Griffiths Problem 1.7

    Griffiths Problem 2.4: Electric field above a square loop of uniform line charge
    Electric field along the axis of a cylindrical shell with uniform surface charge
  • Week of Sept 18 - practice with vectors and vector integrals
    Griffiths Problem 1.55
    Griffiths Problem 1.62 a-d
  • Week of Sept 25 - scalar and vector potentials and Gauss' Law
    Griffiths Problem 1.50
    Griffiths Problem 2.9

  • Week of Oct 9 - fields at charged surfaces, electrostatic pressure, interactions with conductors
    Find the electric field E and electrostatic potential V for a long hollow cylindrical tube which carries a uniform surface charge density σ. Explicitly compute the discontinuity in E, and the discontinuity in the normal derivative of V, at the surface of the cylinder, and show that these results are consistent with the general results of Griffiths Eq. (2.33) and (2.36).
