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 :

Options

  1. A0 . 0628   s
  2. B6 . 28   s
  3. C0 . 628   s
  4. D3 . 14   s

Correct answer

C. 0 . 628   s

Step-by-step solution

Spring force, F = k x Spring constant, k = F x = 10 0 . 05 = 200   N m Time period, T = 2 π m k T = 2 π 2 200 = 0 . 2 π = 0 . 628   s
