A and B are two radioactive substances. The half-life of A is same as the average life of B . The decay constant of B is 3.33 per day. (assume 2=0.70 )

Options

  1. AIf initially A and B have the same number of nuclei, then the ratio of the number of nuclei of A to that of B
  2. BIf the initial amount of A and B are the same, then the ratio of the number of nuclei of A to that of B will g
  3. CIf the initial amount of B is twice that of A , then the number of nuclei of A and B will be the same after 0.
  4. D85.7 % of A will disintegrate in about 3 days.

Correct answer

C. If the initial amount of B is twice that of A , then the number of nuclei of A and B will be the same after 0.
