This going to be a long post ! Orbital Dilemma: i) Why there is opposite phase orbital for s-orbital? [ Couldn't find any representation on the web except for a pic in Ian Fleming's Molecular Orbitals and Organic Chemical Reactions,pg3) *I assert no right over the image,image is referenced...

@mfb Well the defination of solid angle I know is that Area subtended by base of cone at a point. So if I put sphere into the picture (Imagine fitting the sphere into the cone) ,then the maximum surface are captured by the base of the cone is 2pi*r^2 ,not the 4*pi*r^2. The other part certainly...

But Ain't we should consider only the part we face only as per the definition? I asked this question in reference to proof of Gauss Theorem , everything makes sense except the part we don't see? Also let's suppose we consider part we 'don't see then let's draw a simple cone(with no extras like...

@Dale @sophiecentaur I have the e-books on my computer, I can certainly quote the pages : I have noticed that older books like Smythe, JEan and Irodov directly jumps to potential witout referencing work done. In Purcell : Pg 12 Para 3: "s. The force that has to be applied to move one charge...

First of all Thankyou @everyone for taking out your precious time to help me @Dale: I referred every book I can, indiscriminately : From school book to Purcell to Older Books like Smythe and U.Jean to some Russian texts for e.g. Irodov and finally Internet @sophiecentaur @Happiness...

@Nidum : Uh my bad, but how shall one prove that for any closed surface solid angle is always 4pi sr ?

I googled a lot on proof of Gauss theorem and nearly every other proof (on web and so on books) state that solid angle of closed surface is 4pi but I can't find the proof of this nowhere ! I tried setting up the integral but don't know how to proceed furthur : Ω=∫(cosθ/r^2)*dA Also The one...

Hello Everybody! Concept of Solid Angle was pretty much straight forward until they were on surface patches were taken into account which were visualized as base of cone. I am having difficult when 3d Objects like Sphere/Cylinder . We can very easily calculate the respective area and plugin the...

Eh? I still don't understand this, ,if charge is at rest then to move it one need acceleration at first places( which yields KE as byproduct)?

sorry for typo :') [POST Editedd]

Kindly elaborate !.I mean explain the reasoning behind this decision and its implications

I am having hard time understanding the definition of work done to move a charge in an electrostatic field book says that if charge A and B sitting at some position and now if I move the charge say A towards B from arbitrary direction that force required is exactly equal and opposite to the the...

Hello PhysicsForum Community, I know the questions seems to be weird but can you guys who have been admitted to MiT,STanford,etc,care to upload their "Why I" or "Why this ,<univ> is for me" essay" (if guys have a copy with you) because country I...
