Question

A spring stretches 5 cm when mass of 0.5 kg is attached statically. Time period of oscillation is:
  1. A
    0.449 s
    Correct
  2. B
    0.142 s
  3. C
    0.2 s
  4. D
    1 s

Correct answer

0.449 s

Explanation

k = mg/x = 0.5×10/0.05 = 100 N/m. T = 2π√(0.5/100) = 2π×0.0707 = 0.444 s ≈ 0.449 s.
