A pair of parallel conducting plates have potentials of −17 V and 55 V, respectively. An electron is ejected from the plate at potential −17 V and travels to the plate at 55 V. What is the speed of the electron as it strikes the 55 V plate, assuming it left the −17 V plate starting from rest? The mass of the electron is 9.11 × 10−31 kg.
