Coulomb's Explosion

  1. Jan 17, 2010 #1
    Hi, I was wondering about a query on Coulomb's Explosion? Can Coulomb's Explosion occur in macroscopic level? I mean for a large bodies that are visible by naked eyes?

    I suspect that a negatively-charged conducting sphere will start electric-field emission when the electric field at the surface of the sphere overcomes the work function (equivalent to field emission in RF cavities). For a positively-charged sphere, field emission of electrons will not occur, but chunks of positively charged-material will be ejected.
