    How to derive the velocity's direction from a potential

    What if I were given the initial conditions (initial velocity and direction, etc)? Can I determine the direction?

    How to derive the velocity's direction from a potential

    Okay, thanks! It has to be a mistake then.

    How to derive the velocity's direction from a potential

    Alright, so they probably have a mistake there :/

    How to derive the velocity's direction from a potential

    Thanks for the answers :) So I understand that I didn't miss any "formula" connecting the potential and the direction of the velocity... So it thing must be something specific in the potential given in the problem: v(x) = k(x^2-a^2) where |x|<a 0 where |x|>a (k>0) (we were asked...

    How to derive the velocity's direction from a potential

    Hi, I need some help with a problem in my Classical Mechanics undergrad course. We were assigned a problem in which we were given a one dimentional potential (some sort of a parabola). We were asked to determine the velocity's direction at different point, and even though it is somewhat...

    Other Looking for a book to replace Arfken

    Umm can you recommend texts that are more specific about each one of these subjects? About that - I already went through Boas's part about Fourier analysis and it didn't really cover our course.. Same goes with spherical harmonies and boundary problems.. Thanks again

    Other Looking for a book to replace Arfken

    Hi :) Okay so next month I have an exam in the course Mathematical Methods III and I desperately need a good textbook to study from. We covered variation calculus,fourier analysis and partial differential equations including sphrical harmonies (legendre polynomials) and various boundary...

    Electric Fields in Coaxial Cables: Understanding Bound Charge Densities

    Homework Statement http://postimg.org/image/vzhqi8er5/ Homework EquationsThe Attempt at a Solution I understand all the calculations here - http://www.physicspages.com/2012/10/18/coaxial-cable-with-dielectric/ I have one issue that is bugging me though - if λ charge density is distributed over...

    Calculus Best book for theoretical multivariable calculus self-study

    Hi, I'm looking for a good book to study multivariable calculus from that would fit a proof-based undergraduate math course. The emphasis should be on RIGOROUS proofs, theorems and presentation of concepts. I really need a book that would be approachable for self-study with clear and...

    Conductor in a capacitor problen (E&M)

    Here V1 = V2 (it is a given), but the capacity grows... And that results in a negative kinetic energy...

    Conductor in a capacitor problen (E&M)

    Thank you! And what about (b)? The problem with (b) is that using your equation results in a negative kinetic energy, which is physically impossible as far as I know... So I suppose we have to take the work done by the battery into consideration, but I don't know how this can be done here.

    Conductor in a capacitor problen (E&M)

    1. The question: This question is from purcell's E&M book (3.71). (a) The plates of a capacitor have are A and separation s (assumed to be small). The plates are isolated, so the charges on them remain constant, the charge densities are +-σ. A neutral conducting slab with the same area A but...
