Spring Systems

A spring is stretched by 5 cm by a force 10 N. The time period of the oscillations when a mass of 2 kg is suspended by it is -

Show answer and solution

Answer: (a)

  1. k=Fx=100.05=200 N/mk = \frac{F}{x} = \frac{10}{0.05} = 200\text{ N/m}.
  2. T=2π2200=2π×0.1=0.628 sT = 2\pi\sqrt{\frac{2}{200}} = 2\pi \times 0.1 = 0.628\text{ s}.
  3. So the answer is (a) 0.628 s.
