1. The problem statement, all variables and given/known data In class today my physics professor proposed this question and left it unanswered: (We're beginning to study Gauss' Law) "Lightning strikes Manhattan in a brilliant display, each strike delivering some 10,000 amperes of electron flow from the cloud base to the ground. How wide is a lightning strike. Since it can be seen from kilometers away, is it as wide as say, one of the huge manhattan buildings?" I've beginning thinking about this all day and can't seem to come to any conclusions about it, as i have never really thought about that. My initial thoughts are that the lightning strike seen is actually the flux form the electric field caused by the lightning?
