A radioactive sample S_(1) having an activity 5 mu Ci has twice the number of inucle as another sample S_(2) which has as activity of 10 mu Ci . The half lives of S_(1) and S_(2) can be

A radioactive sample S_(1) having the activity A_(1) has twice the number of nuclei as another sample S_(2) of activity A_(2) If A_(2)=2A_(1) , then the ratio of half life of S_(1) to the life of S_(2) is
