Homework Help: Electric flux of a particle

  1. Sep 25, 2009 #1
    1. The problem statement, all variables and given/known data
    A particle with charge Q= 5.00 microcoulombs is located at the center of a cube of edge L= 0.100 m. In addition, six other identical charged particles -q are positioned symmetrically around Q. Determine the electric flux through one face of the cube.

    2. Relevant equations

    Flux= S E dA (the S is suppose to be an integral symbol)

    3. The attempt at a solution

    Flux= S E dA + S E dA

    is this right so far? if so not sure what I need to do next, if not what do I need to do? thanks

    Hi tag16! :smile:

    (have an integral: ∫ :wink:)
    For the charge at the centre, the flux is easy to find … just find the flux through all 6 faces, and divide by 6. :wink:

    But for the other charges, yes, I think you'll have to do some integrating. :smile:
