A radioactive nuclide A decays to nuclide B which further decays to C. Their disintegration constant are λ1 and λ2 respectively. At t = 0 only nuclei A are present. Number of nuclei A at t = 0  is N0
  • a)
    rate of decay of A will first increase and then decrease
  • b)
    number of nuclei of B will first increase and then decrease
  • c)
    if λ2 > λ1, then activity of B will always be higher than activity of A
  • d)
    if λ1 >> λ2, then number of nucleus of C will always be less than number of nucleus of B.
Correct answer is option 'B'. Can you explain this answer?
