Question

5. (1 point) An electron is thermionically emitted from a hot cathode and is accelerated between the cathode to an anode which are respectively held at electric potentials of 100 V and2950 V. (a) Calculate the kinetic energy (EKE) acquired by the elec-tron in joules. (b) Calculate the kinetic energy (EKE) acquired by the elec-tron in electronvolts. (c) Calculate the velocity (v) acquired by the electron. Express you answer in terms of the standard SI units for the quantity.
