so... what is the answer to the question about electrons' speed? I tried myself.. If kinematic energy is Ek = 1/2*q*v^2 (q for charged particles instead of m) and it equals the Work done, W = q*V, then the speed would be v = sqrt(V/2). Is that right? or my thinking is completely wrong.. Can we have an answer?
