In this class, you look at a particle moving electrical in the field and you assume that the potential of this particle is given by, it's given by q5 minus q.
00:14
Qa dot r, right? and it said if i is scalar potential, a is vector potential.
00:22
And then you say, what is like a larger? the lagrangeur, i think, according to the question, probably he wants to say it's a half a v squared over two, minus vr right.
00:33
And that is m2r dot squared minus vr.
00:40
And then you asked to find the conjugate conjugated colonial momentum p, which of course by question, by definitions given by v, right? and that will be given by, i think there's something wrong with this question.
00:59
This must be r dot, right? i think there must be something wrong with the question.
01:04
So it must be a dot...
