Many thanks, it's clear now.

The EM Lagrangian is $$\mathcal{L} = -\frac{1}{2}[(\partial_\mu A_\nu)(\partial^\mu A^\nu) - (\partial_\mu A_\nu)(\partial^\nu A^\mu)]$$ In the QFT notes from Tong the EM Lagrangian is written in the form $$\mathcal{L} = -\frac{1}{2}[(\partial_\mu A_\nu)(\partial^\mu A^\nu) - (\partial_\mu...

I'm reading Modern Particle Physics by Mark Thomson and watching Susskind's lecture on QM. In Thompson's book, equation (2.41) the wavefunction is expressed in terms of complete set of states of the unperturbed Hamiltonian as \Psi(\textbf{x}, t) = \sum_{k} c_k(t)\phi_k(\textbf{x})e^{-iE_kt}...

I don't know how to start solving attached problem (3.126 from Irodov) because I can't identify any series or parallel connection between capacitors. I came to an idea that I should "break" capacitor C3 into two capacitors and then get two series and one parallel connections. Any ideas?

Two infinite conducting plates 1 and 2 are separated by a distance l. A point charge q is located between the plates at a distance x from plate 1. Find the charges induced on each plate. I solved this problem assuming (intuitively) that a potential difference between plate 1 and 2 equals 0 and...

You are absolutely right so please accept my apology. Regards, Marko

I attached my solution in pdf format. Similar solution you can find on this page http://irodov.nm.ru/3/resh/3_10.gif

The whole problem is a little bit fuzzy to me (E', Eokp, E and relations between them), so it would be very helpful if you could explain main steps in solving this problem (without doing integration, just basic steps and formulae). Thanks.

A metal ball or radius R=1.5[cm] has a charge q=10e-6[C]. Find the modulus of the vector of the resultant force acting on a charge located on one half of the ball. I found a solution on http://irodov.nm.ru/3/resh/3_69.gif but I don't understand explanations regardind to the problem so I would...
