Two radioactive materials X1 and X2 have decay constants 10λ and λ respectively. If initially they have the same number of nuclei, then the ratio of the number of nuclei of X1 to that of X2 will be 1/e after a time then the ratio of the number of nuclei of X1 to that of X2 will be 1/e after a time Two radioactive materials X1 and X2 have decay constants 10λ and λ respectively.
