5) A a planar 'cathode', which is held at electric potential V=0, is parallel to a planar anode, held at a potential V_A, and with a separation d. The separation d is much smaller than the area of the two electrodes, so edge effects can be neglected. (5 pts) Electrons Cathode (V=0) Anode ( VA) • What is the potential between the Anode and Cathode as a function of x? • Assuming individual electrons are released from the cathode, and start from rest. What is their speed v at a point x (0 <x<d)?
