1. The problem statement, all variables and given/known data An electron in a benzene molecule makes a reasonable approximation to an electron confined to a hoop. If the radius of the benzene molecule is about 5x10-10 m, and the electron has the lowest allowed angular momentum of h/2π, what is the velocity of the electron? (You may wish to recall the electron mass is 9x10-31 kg, and angular momentum is L = rp = rmv.) 2. Relevant equations I'm not entirely sure. 3. The attempt at a solution I'm in a really poorly run workshop based class, so we have no text book and the packets we were given are completely not at all helpful here.
