The half-life period of a radioactive element X is same as the mean life time of another radioactive element Y. Initially both of them have the same number of atoms. Then

View answer and explanation

Correct option: C

Y will decay at a faster rate than X initially

Option A (5) is correct because setting the time constant of the RC circuit equal to the average life of the radioactive sample ensures the ratio of charge to activity remains constant.
