Homework Statement I am trying to calculate the dipole moment of a cylinder of volume charge density ##\rho_0## of radius ##R## and height ##H## with is center coinciding with the origin. My guess is that it should be 0 because of the symmetry but I am not able to show it. Below is my...

I understand that in a two body problem under central force, corresponding to a potential V(r)(assume one body is massive compared to the other so that its motion is negligible), conservation of angular momentum implies the motion of the body to be in a plane spanned by position r and momentum p...

Please check, updated the question with source of reference.

OK, let's assume that a, b and c are basis vectors in 3D space. But how does that lead to the conclusion "the coefficient α cannot involve any overlap of v with either b or c" starting with the equation v = α a + β b + γ c ".

Didn't notice that. I copied the text from a page. It turned out like this.

Hi Dauto, I thought of that, it's clear. But I'm trying to understand the author's intuition behind the statement "the coefficient α cannot involve any overlap of v with either b or c" starting with the equation v = α a + β b + γ c ".

As far as I understand, when we try to resolve v in the basis of a b and c according to equation (1), the coefficient α, β, or γ are scalar values, which means they must be the resulting from the dot product of vectors. What's wrong in assuming that α can contain the dot product among any two...

Hi, I came across this statement while I was reading an article on resolution of vector in arbitrary basis. "v = αa + βb + γc ---(1) , where a, b and c are three independent vectors. we observe that the coefficient α cannot involve any overlap of v with either b or c ; β cannot involve any...

Hello everyone, I have an MTech in Electrical Engg from IIT Madras(India). As I have been considering to change my field I want to do MSc. in Physics. My question is, am I allowed to do it in the first place after being and Mtech. in Engineering already? Thanks

Hello everyone, I need advice related to my career. I have been working in semiconductor company as an engineer for 2 years now after gradating from IIT Madras(one of the reputed technical institution in India) with a Dual Degree(BTech + MTech in 5 years) in Electrical Engg with VLSI as...

Thanks mfb for the response. I have got one more question. When we say the LASER is coherent, what does it mean? What does it mean to be non-coherent? What does a monochromatic, non-divergent and COHERENT light has that a monochromatic, non-divergent and NON-COHERENT lacks? Does it have less...

1. Won't the electrons get knocked out of the atom during the pumping action instead of just getting excited to higher energy level in LASERS? 2. why doesn't the electron in meta stable state(higher energy state) go to much higher energy level during STIMULATED emission instead of losing energy...
