Dec 15 | Is velocity, (the time derivative of r_0), constant? | You don't need that information. |
Dec 15 | I have a question about the external force in problem 3 of the take home exam.
Can we assume that the force only exists for times t > 0 or does it act for all times? | You should not make any assumptions about F. |
Dec 15 | P 1. Should I consider that the dipole is oriented in the same direction for all time? | You do not need to assume anything about the direction of the dipole. |
Dec 15 | In problem 2, we need to find current in the central arm only and not in the other two arms, right? Just making sure! | Yes. |
Dec 16 | In problem #1 part b, is it okay if our expression for Qij contains vectors as well as index notation? Or should the answer be completely in terms of variables in index notation? | That's fine. |
Dec 16 | In the expression for the electric dipole field that is listed in problem 1, the units of the two terms in the brackets do not seem to match. Should the R vector in the parentheses be an R unit vector instead? | Oops. Of course. Thanks for catching that. |
