Problem Sets to be completed in your corresponding PSNs by noon Sun. May 14.

• EM PS#15: Griffiths: 10.12, 10.13, 10.14, 10.24 || 10.16, 10.23, 10.29, 10.30.
• QM PS#12: Townsend: 9.9, 9.12, 9.16, 9.18, 9.19, 9.20, 9.21, 9.22. Notes: 9.17 is not assigned for this set, but it’s a canonical problem; I handed out an appendix from Eisberg & Resnick last week that covered this problem (if you missed picking up the handout, it is on the side counter in the Cave).
