Anode- .cathode A hot cathode rod is placed such that it lies in the along the axis of a circular anode ring as shown in Figure. Charge density of the ring is A = 1.7nC/m and the radius is R= 19 cm a) Assume that the potentail at infinity is zero, i.e. Voo = 0. What is the potential at the center of the ring? b) If the potential of the rod is given V = -3 volt, calculate the energy required for a charge of g = 9µC to travel from the cathode to the center of the anode. The distance between the anode and cathode is d= 8 cm. c) When the charge qı reached at the center of the anode what would be it's speed? Give that the mass of the ma = 51.1706705844 × 10-18 kg. Speed of g at the center of the anode Give your answer to at least two significance digits. d) How many electron will be required to produced q?
