I think there is some problem in understanding here. The formula En=-Z2RH/n2 can be used only for Hydrogen like atoms i.e. we can use this formula for He+ and not for ground state of Helium. Ground state electron configuration of Helium is 1s2 while the configuration for He+ is 1s1 same as of...

I just confirmed it and it says by any method. And potential at any arbitrary point in the space.

Homework Statement Let a charge oscillate on a straight line between -a to +a with a frequency ω and according to the law: κ (x.t) = κ° sin(πx/a) e^(-iωt) I have to find the following: 1. Vector potential in the dipole approximation 2. Integral of the intensity of radiation Homework...

Ahh. We follow CGS in our university. Our textbook (L&L) is CGS based.

Addition of which additional constant? And also, in my case, will the potential be calculated as Φ = ∫ (σ(x,y)/ r) ds

This one? Φ = ∫ (ρ×dV)/r

Well, in what another way can I approach this problem? And if the plate was finite, is my formula right for that case?

Homework Statement A plane z=0 is charged with density, changing periodically according to the law: σ = σ° sin(αx) sin (βy) where, σ°, α and β are constants. We have to find the potential of this system of charges. Homework EquationsThe Attempt at a Solution [/B] I...

Mentor note: Moved to homework section A conical wheel is rolling (without slipping) around a fixed axis OZ as shown in the figure. The velocity of point C is vc = at. The direction of the velocity of C is shown by a cross i.e. along negative x-axis. We have to find the angular velocity...

As far as I remember, you cannot directly apply for this program right after class 12th. You have to complete 1 year in any of the Indian colleges recognised in Germany and only then you can apply for this program.

Thank you, everyone for making me understand this. Sorry for taking a little long to reply. And yes, they were linear oscillations

Thank you very much, everyone. I understood it but took a little time to reply back. And yes, they were linear oscillations.

Yeah, non-uniform. That is what I intended to write, was a typo.If we keep left face of the gaussian cylinder inside the positive half of the plate, the flux through that surface would be E.ds and would be positive. If we keep left face of the gaussian cylinder inside the negative half of the...

The magnitude of forces on both the charges of the dipole will be equal as they're at an equal distance from the centre. I am sure about this. Talking about the gaussian surface, What will be the gaussian surface, we use the formula ∫E.ds = 4πq or q/ε Here, the what will be E through the right...

Is this the gaussian surface you were talking about?
