  • Electrostatics: Gauss Law Problem Finding the Flux through a . . .
    I think the answer to part (i) is given wrong The flux can't be zero because there is a charge Q 2 enclosed by the shell So, the flux should be Q 2 divided by permittivity of free space Now in part (iii), the force on charge at point A is given correct However, the force on charge at centre
  • Electric field Difference between Electrostatics and Electrodynamics
    In electrostatics (where the charges are not moving): a) Electric fields are time- independent but position-dependent b) Electric fields are always zero inside a charged or uncharged conductor At the conductor surface, the E field is nonzero and perpendicular to the surface itself
  • Is Gravity Just the Electrostatic Force? - Physics Forums
    It's pretty easy to disprove this idea, even on the level of Newtonian gravity: First of all the sources of the electrostatic field are charge distributions at rest, those of the gravitational field are mass distributions, and in electrostatics like-sign charges repell, while the always positive (i e , like-sign) masses attract each other
  • Div D, div E. What rho is it. (electrostatics) - Physics Forums
    I know that the D field has to do with free charges So when we write Maxwell's equation ##\\vec \\nabla \\cdot \\vec D = \\rho## we mean rho as the free charge density which does not include the bound charges also known as polarized charges I know that the E field has to do with both the free
  • What career opportunities are available in electrostatics? - Physics Forums
    Electrostatics don't really happen in nature Everything tends to move, making everything fairly complicated
  • Books on Electrostatics for IIT Prep - Physics Forums
    can anyone suggest me books on electrostatics and electromagnetism at a graduate level as iam preparing for indian institute of technology (iit) it would be a great help for me If you are going to be in a physics department then, as others have stated, Jackson is the standard graduate-level book
  • Electrostatic Experiments: Why Not Work on Humid Days? - Physics Forums

  • Which Book Best Explains Electrostatics and . . . - Physics Forums
    Hey PF, I've studied electrostatics and electrodynamics in the past years in high school, but it was just school-study I never had a chance to thoroughly understand them, I'd like to read and learn more about electrostatics and electrodynamics on my holiday, so I'd like anyone to
  • Dimensions of K (the constant in Coulombs Law) - Physics Forums
    Doc, i think there is more to Chen's question than that 3 or 4 years ago, I've had a lot of discussions on sci physics research about dimensions, fundamental constants, etc, particularly of [tex] G, c, \hbar, \epsilon_0 [ tex]
  • Electric potential due to a solid sphere - Physics Forums
    Hello Guys! This is my first post so bear with me I am currently studying the basics of electrostatics using the textbook "Introduction to electrodynamics 3 edt - David J Griffiths" My problem comes when i try to solve problem 2 21 Find the potential V inside and outside a uniformly
