  1. Question 1

    Q1. The velocity of the electron in the nth orbit is given by vn = v1 / n. If v1 = 2.2 x 10⁶ m/s, what is v3?

    • A) 7.33 x 10⁵ m/s
    • B) 2.2 x 10⁶ m/s
    • C) 1.1 x 10⁶ m/s
    • D) 4.4 x 10⁶ m/s

    Answer: 7.33 x 10⁵ m/s

    Explanation: v3 = v1 / 3 = 2.2 x 10⁶ / 3 = 7.33 x 10⁵ m/s.
