  1. Question 1

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

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

    Answer: 7.33 * 10⁵ m/s

    Explanation: Using vn = v1 / n, for n = 3, v3 = 2.2 * 10⁶ / 3 = 7.33 * 10⁵ m/s.
