What is the speed of the blood?

  • Thread starter hotstuff
  • Start date
The artery in Figure 22-11 has an inside diameter of 2.30 mm and passes through a region where the magnetic field is 0.065 T.

(a) If the voltage difference between the electrodes is 175 µV, what is the speed of the blood?

quite honestly, i do not know how to go about this one maybe v= E/B BUT E is not given and i don,t know of an equation to acquire E from the above eaqn, since no charge is given. how should i go about. thks
you can find E because you know the potential difference and the geometry of the blood vessel. The magnitude of the electric field depends on the distance a point is from a potential difference.
thank very solvable now :)
