  1. Question 1

    Q1. In a discharge tube, the velocity of the produced cathode rays is primarily dependent on which of the following experimental parameters?

    • A) The material of the cathode
    • B) The potential difference applied
    • C) The type of gas in the tube
    • D) The size of the discharge tube

    Answer: The potential difference applied

    Explanation: Voltage determines the energy/velocity of cathode rays; the nature of the cathode material does not change the ray properties.
