Guys, please look at the following question
I am aware of how to take a dot product of 2 vectors whose i,j,k components are given. My issue is with both integrals. I feel it should be '-dx ' rather than dx because x is decreasing , same as in '-dy'.and I'm taught that if x is decreasing then...
Hello! I am new to the differential version of classical physics, and I am trying to work how to derive kinetic energy from some pre-assumed equations:
Assume that we know: ##\ddot{z} = 0## and ##m\ddot{\textbf{r}} \cdot \dot{\textbf{r}} = 0##
This results in $$\frac{1}{2}m\dot{r}^2 = W =...

Hi, I have the following problem, maybe someone relates.
I am about to finish my Bachelors Degree in Physics and must say it was a very unenjoyable road. I started it because since forever I was fascinated by the "great" ideas trying to explain reality that lie behind physics, i. e. Quantum...
I am in the last year of my high-school with an aspiration to do a double-bachelor in Physics and Math. I am not sure if I am capable of doing so (I am not the smartest), but it is really one of my dreams to study both subjects, so I will try.
However, sometimes I experience some difficulty in...
Hi, I was practicing some problems on the magnetic field and the electromotive force, when I got stuck on these two exercises. Could you help me figure out how to proceed?
In the first problem, I tried to find the magnetic field flux by multiplying the induced current for ∆t and R. Should I now...
I am a person who likes to think deep and can't keep himself from delving deeper into concepts. Even though math is the subject in which I outshine my counterparts, it is physics that I find more fascinating. Also I feel that physics gives math a sense of direction to work upon.
But I am a...
A certain field has a singularity at the origin, and the divergence of its curl is zero at any point outside the origin, but surface integral of the curl is not zero in the area of any closed surface containing the origin. So how should the Stokes theorem related to this field be expressed at...

Hypothetical: Approximately how far from Earth would a star the size of the sun have to be for an object the size of a quantum particle to cause a total eclipse of that star when orbiting the Earth at a distance equal to that of Earth to the center fro the moon?
This might be total nonsense, but the thought popped into my head while I was trying to get to sleep, so I thought I see if I could find any advanced help with the following hypothetical:
If light were instantaneous, how far from Earth would the sun have to be to cause a quark orbiting in place...
Hello,
So, I'm looking for some advice from people here who have experience studying physics outside of an academic program. Recently, I've started Griffiths E&M. Although it hasn't been long, I've been having an absolute blast: like, heart-fluttering, "helping me with suicidal depression"...
