A spring has a certain mass suspended from it and its period for vertical oscillations is ' T₁ '. The spring is now cut in to two equal halves and the same mass is suspended from one of the halves. The period of vertical oscillations is now ' T₂ '. The ratio T₁ / T₂ is

Options

  1. A2
  2. B2
  3. C1 2
  4. D1 2

Correct answer

B. 2

Step-by-step solution

T ₁=2 m k . Also, spring constant ( k ) 1 Length (l) When the spring is half in length, then k becomes twice. aligned & T ₂=2 m 2 k & T ₁ ~T ₂ = 1 1 2 = 2 aligned
