Question
Please answer and show how you got the answer:
Suppose a diode consists of a cylindrical cathode with a radius of 0.1cm , mounted coaxially within a cylindrical anode with a radius of 0.307cm . The potential difference between the anode and cathode is 379V . An electron leaves the surface of the cathode with zero initial speed (nu initial = 0). Find its speed nu final when it strikes the anode. Express your answer numerically in meters per second. What is the electric field at a point midway between the anode and cathode?
