A factory produces a radioactive substance A at a constant rate R which decays with a decay constant ` lambda` to form a stable substance. Find (a) the number of nuclei of A and (b) number of nuclei of B, at any time t assuming the production of A starts at `t=0`. (c ) Also, find out the maximum number of nuclei of `A` present at any time during its formation.

Text Solution

Verified by Experts

Maximum number of nuclei of 'A' present at any time during its formation = `R/(lambda)`
