## Question

### Solution

Correct option is All the lead present in the ore is the final stable product of . It means that the number of nuclei of present is equal to the number of nuclei of decayed.

Let the number nuclei of be N. Then, the number of nuclei of present in the ore is 3N.   .   If, in a radioactive substance, initially and after the time t, the number of nuclei be N0 and N’ respectively, then        .
