I didn't quite know if this is in the right section since it's kinda broad question.

This semester I have classical electrodynamics and soon I'll have first test.

So far we're doing electrostatics, and if we didn't solve problems in class I would have no idea where to start :\

Some of the problems are very hard and challenging (we did some problems from Batygin, Toptygin, problems in Electrodynamics), and I wonder how did the ppl even got the idea to start solving? :\

Do you have any advice on how to study it and how did you cope with sth so complicated (atm even quantum physics seems easy :( )

Thanks...

You need to be very strong in vector calculus to master electromagnetism. Study both vector calculus and the electrostatics material. If you are behind now you will get even more behind later, so take whatever opportunity you have to either now or shortly learn all that you can.
 
And what about concrete problems, are there any solved problems book that can help me with that?
 
I think Griffiths Electrodynamics is the best textbook I've ever had. Get it from your library.
 
I second Mindscrapes advice. Solving problems is only useful once you have mastered the material. Mastering the material means reading multiple books until you understand each concept. (Griffiths is excellent, Reitz and Milford might be useful since they have a different, more engineering-oriented, slant approach). Bolster your math skills. Get help from your TA's, prof and other students.

If you want to practice problems, get Schaum's outline on E&M. I suggest using it like this: study a chapter or topic in your book, then work a problem as a test of your comprehension. If you don't know how to start, then go back to the books. When you can work most of the problems, you're ready to proceed to the next topic.

Don't get discouraged. Physics is hard for most everyone.
 
Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
The value of H equals ## 10^{3}## in natural units, According to : https://en.wikipedia.org/wiki/Natural_units, ## t \sim 10^{-21} sec = 10^{21} Hz ##, and since ## \text{GeV} \sim 10^{24} \text{Hz } ##, ## GeV \sim 10^{24} \times 10^{-21} = 10^3 ## in natural units. So is this conversion correct? Also in the above formula, can I convert H to that natural units , since it’s a constant, while keeping k in Hz ?
