1. The problem statement, all variables and given/known data two oppositely charged students bring thier fingers toward each other. a spark jumps between their fingers when brought 7.0 cm apart. A) what is the electric field between fingers when sparking occurs B) what is the potential difference between the two students 2. Relevant equations q=fe q=vc f= kq1q2/r^2 3. The attempt at a solution i think i can get part b if i get a but i dont really have aclue where to even start i know e=q/f but what does distance have to do with it?? can someone help me where to start??
