    What equilibrium distance to use for E of a vertical spring

    The potential energy of the mass will decrease. In principle, in order to satisfy the conservation of energy, the energy which is increased when it gets stored in the spring is canceled out by the gravitational potential energy which is lost, assuming you are at equilibrium at both times (so...

    What equilibrium distance to use for E of a vertical spring

    I just wanted to confirm whether the idea I have about vertical springs is correct or not. Suppose you have an ideal (massless) spring oriented vertically, and suspended from a block in the air, which in turn is mounted on a stand and placed on a desk. The distance from the desk (or the base of...

    Simple question on W boson decay products

    Thank you, that was very helpful. As a side note let me just say I am really enjoying drawing these Feynman diagrams! :D Also I was a bit sloppy I think I should not have written 'only', I meant to say in the context of the electron lepton only. Because of course it can decay into muons and...

    Simple question on W boson decay products

    Hi, I'm working on an assignment in which the following reaction takes place: \nu_e e^- \rightarrow \nu_e e^- And I'm wondering whether its possible to have an electron neutrino and an electron annihilate to form a W^- boson, after which that boson decays into a \nu_e e^- pair...

    Determining the magnetic field on the axis of a uniformly magnetized cylinder

    Sorry if double-posting not allowed, I just don't see the edit function for my previous post. Anyway! It worked out well. The second part of the question was pretty straightforward as well. Guess this thread is resolved

    Determining the magnetic field on the axis of a uniformly magnetized cylinder

    Thanks for the reply, I actually went to my teaching assistant at my university and basically he shared the same view. I know that my problem is equivalent to having a tightly-wound solenoid, since the magnetization produces a surface current along the azimuthal direction (counter clockwise if I...

    Determining the magnetic field on the axis of a uniformly magnetized cylinder

    Homework Statement A cylindrical volume of length L, radius a, is given a uniform magnetization M along its axis (call it the z axis). The question is to first find the bound currents, then use them to find the magnetic field B, as well as "the auxiliary field" H - but only along the axis of...
