  1. Question 1

    Q1. The velocity of the electron in the nth orbit is given by vn = 2.2 * 10^6 / n m/s. What is the velocity in the 2nd orbit?

    • A) 1.1 * 10^6 m/s
    • B) 2.2 * 10^6 m/s
    • C) 1.1 * 10^7 m/s
    • D) 2.2 * 10^7 m/s

    Answer: 1.1 * 10^6 m/s

    Explanation: Substitute n = 2 in the given formula: vn = 2.2 * 10^6 / 2 = 1.1 * 10^6 m/s.
