NEET Physics Question (2025) — Solution

Question

Two identical point masses P and Q , suspended from two separate massless springs of spring constants k _1 and k _2, respectively, oscillate vertically. If their maximum speeds are the same, the ratio (A_Q / A_P ) of the amplitude A_Q of mass Q to the amplitude A_P of mass P is :

Options

  1. A. k _2 k _1
  2. B. k _1 k _2
  3. C. k _2 k _1
  4. D. k _1 k _2

Answer

D. k _1 k _2

Step-by-step solution

aligned & Given m _ P = m _ Q \\ & Also ( V _ )_ P = ( V _ )_ Q \\ & A _ P _ P = A _ Q _ Q \\ & A _ P k _1 ~m _ P = A _ Q k _2 ~m _ Q [ = k m ] \\ & A _ Q A _ P = k _1 k _2 aligned
