Time PeriodEasyQuestion 31103

Question

Time period of a mass-spring system (mass m, spring constant k) is:
  1. A
    2π√(k/m)
  2. B
    2π√(m/k)
    Correct
  3. C
    √(m/k)/2π
  4. D
    2π√(mk)

Correct answer

2π√(m/k)

Explanation

T = 2π/ω = 2π√(m/k). Heavier mass or weaker spring means longer period.
