  1. Question 1

    Q1. The equation of motion of a particle is d²x / dt² + kx = 0. The frequency of vibration is

    • A) 1 / 2 π √(k)
    • B) 2 π √k
    • C) √(k) / 2 π
    • D) 1 / 2 π √k

    Answer: 1 / 2 π √(k)

    Explanation: The given equation represents SHM with angular frequency ω = √k. Frequency, f = ω / 2 π = 1 / 2 π √k.
