Metal sphere charge

  1. Jun 27, 2008 #1
    Just wondering: If a metal sphere is charged, will the extra charge be uniformly distributed over the volume of the sphere.

    i think that it will? but not sure about it being uniformly distributed.

    What is the value of the electric field inside a [charged] conductor?

    Correct. Having charges distributed over the entire volume of the sphere, would mean that there must be some net charge inside the sphere, which would result in a non-zero electric field. So, where must the charges be distributed?

    sorry, i really don't know where the charges should be distributed. im guessing the outer surface of the sphere?

    Correct :approve:. If the charges are uniformally distributed on the outer surface of the sphere, then this results in the electric field inside the sphere being zero.
