In an electron gun, electrons are accelerated from the cathode (negatively charged plate)toward the anode (positively charged plate). If the potential difference between the cathode and anode is 0.9 kV, at what speed do the electrons move as they reach the anode? Assume that the initial kinetic energy of the electrons as they leave the cathode is negligible.

You are welcome to approximate g as 10 m/s2, 0 as 9 × 10-12 C2/(N m2), the mass of the electron as 9 × 10-31 kg, and the charge of the electron as -2 × 10-19 C to obtain numbers. See how close you come toreaching a number without the use of a calculator.
