In the notes, we considered a situation where the shock was moving in the upstream rest frame, so that in the shock frame the upstream velocity was normal to the shock. Thus, there should be a term vx*Bz in the Ey electric field that adds another term to the de H-T velocity in equation 4.36. Because of this confusion, I just gave 10 points to everyone on this problem.</p> <ul> <table width="100%"> <tr valign="top"> <td class="emptytag"></td> <td> <a href="/classes/2017/spring/Phys 8611.001/downloads/440732-ps3_solutions.pdf" title="797&nbsp;Kbytes, application/pdf">Problem Set 3 Solutions</a> <small>| <a href="/classes/2017/spring/Phys 8611.001/downloads/440732-ps3_solutions.pdf?download=1" title="797&nbsp;Kbytes, application/pdf">Download</a></small> </td><td align="right"> <small><i>posted 4-Apr-2017 at 12:25PM</i></small> </td></tr> </table> </ul><ul> <table width="100%"> <tr valign="top"> <td class="emptytag"></td> <td> <a href="/classes/2017/spring/Phys 8611.001/downloads/433502-8611ps3_2017.pdf" title="85&nbsp;Kbytes, application/pdf">Problem Set 3</a> <small>| <a href="/classes/2017/spring/Phys 8611.001/downloads/433502-8611ps3_2017.pdf?download=1" title="85&nbsp;Kbytes, application/pdf">Download</a></small> </td><td align="right"> <small><i>posted 24-Feb-2017 at 2:16PM</i></small> </td></tr> </table> </ul>2017-04-04T17:28:12ZRobert Lysakcid:58611.eid:433492.updated:2017-04-04 12:28:12Problem Set 3 (Due March 27) (Updated)2017-02-10T17:42:57Z<ul> <table width="100%"> <tr valign="top"> <td class="emptytag"></td> <td> <a href="/classes/2017/spring/Phys 8611.001/downloads/433512-ps2solutions.pdf" title="341&nbsp;Kbytes, application/pdf">Problem Set 2 Solutions</a> <small>| <a href="/classes/2017/spring/Phys 8611.001/downloads/433512-ps2solutions.pdf?download=1" title="341&nbsp;Kbytes, application/pdf">Download</a></small> </td><td align="right"> <small><i>posted 24-Feb-2017 at 2:17PM</i></small> </td></tr> </table> </ul><ul> <table width="100%"> <tr valign="top"> <td class="emptytag"></td> <td> <a href="/classes/2017/spring/Phys 8611.001/downloads/430052-8611ps2_2017.pdf" title="76&nbsp;Kbytes, application/pdf">Problem Set 2</a> <small>| <a href="/classes/2017/spring/Phys 8611.001/downloads/430052-8611ps2_2017.pdf?download=1" title="76&nbsp;Kbytes, application/pdf">Download</a></small> </td><td align="right"> <small><i>posted 10-Feb-2017 at 11:43AM</i></small> </td></tr> </table> </ul>2017-02-24T20:17:12ZRobert Lysakcid:58611.eid:430042.updated:2017-02-24 14:17:12Problem Set 2 (Due February 24) (Updated)2017-01-24T18:05:35Z<ul> <table width="100%"> <tr valign="top"> <td class="emptytag"></td> <td> <a href="/classes/2017/spring/Phys 8611.001/downloads/430062-Problem_Set_1_solutions.pdf" title="394&nbsp;Kbytes, application/pdf">Problem set 1 Solutions</a> <small>| <a href="/classes/2017/spring/Phys 8611.001/downloads/430062-Problem_Set_1_solutions.pdf?download=1" title="394&nbsp;Kbytes, application/pdf">Download</a></small> </td><td align="right"> <small><i>posted 23-Feb-2017 at 1:30PM</i></small> </td></tr> </table> </ul><ul> <table width="100%"> <tr valign="top"> <td class="emptytag"></td> <td> <a href="/classes/2017/spring/Phys 8611.001/downloads/425352-8611ps1_2017.pdf" title="95&nbsp;Kbytes, application/pdf">Problem Set 1</a> <small>| <a href="/classes/2017/spring/Phys 8611.001/downloads/425352-8611ps1_2017.pdf?download=1" title="95&nbsp;Kbytes, application/pdf">Download</a></small> </td><td align="right"> <small><i>posted 27-Jan-2017 at 10:06AM</i></small> </td></tr> </table> </ul>2017-02-23T19:30:19ZRobert Lysakcid:58611.eid:425342.updated:2017-02-23 13:30:19Problem Set 1 (Due February 10) (Updated)2017-02-23T16:45:02Z<p>Note that there will be no class on March 6-10 since I will be out of town, which means 2 weeks off since the next week is spring break.
