Charges inside a metal sphere will tend to go towards

  1. Feb 12, 2017 #1
    1. The problem statement, all variables and given/known data
    A metallic sphere is charged. Where will the charges go?
    At center or on surface or uniformly distributed.

    2. Relevant equations
    I think it should be uniformly distributed. Cause that's why we have terms like volume charge density like we do q/volume.

    3. The attempt at a solution
    It was actually in the big exam that I was talking about, and I answered that charges will be uniformly distributed.
    Is that the right answer? Results are out on 28 march.

    i think charges will go to the surfaces
    if there is excess charge(suppose +ve) inside the metallic sphere in static situation it will produce electric field.then free electrones move to the +ve charge to neutralize it.movement of free electrones cause +ve charge somewhere else.ie,the metallic sphere tries to make electric field inside=0.so +ve charges move towards the surfaces and alligned there so that electric field inside=0 and has electric field outwards
    1.inside a conductor,electrostatic field is 0
    2.at surface of charged conductor E.F is normal to surface
    3.electrostatic potential is constant throughout the conductor
    4.the interior of a conductor has no excess charge

    Oh ... another wrong answer i gave at the exam. it's a disaster.:frown:
    Thanks for the reply.
