Question

The half life period of radioactive element x is same as the mean life time of another radioactive element y. Initially they have the same number of atoms. Then :

(1) x–will decay faster than y.

(2) y– will decay faster than x.

(3) x and y have same decay rate initially and later on different decay rate.

(4) x and y decay at the same rate always.

Answer 1

 Correct Option is (2) y– will decay faster than x.

⇒ y will decay faster than x
