JEE Main 2025 — 4 April, Evening Shift — Question 54

A radioactive material PP first decays into QQ and then QQ decays to non-radioactive material RR. Which of the following figure represents time dependent mass of PP, QQ and RR ?

  1. Option A:
    Option A figure
  2. Option B:
    Option B figure
  3. Option C:
    Option C figure
    Correct
  4. Option D:
    Option D figure

Answer: C

Step-by-step solution

P→Q→RP \rightarrow Q \rightarrow R Final mass of RR will be equal to initial mass of PP and mass of

PP is continuously decreasing with time
