Two radioactive materials have decay constant `5lambda&lambda`. If initially they have same no. of nuclei. Find time when ratio of nuclei become `((1)/(e))^(2)` :

Two radioactive materials A_(1) and A_(2) have decay constant 5lambda and lambda respectively. If initially they have the same numberof nuclei, then ratio of nuclei of A_(1) to A_(2) will be (1)/(e) after a time :

Two radioactive materials X_(1) and X_(2) have decay constant 11 lambda and lambda respectively. If initially they have same number of nuclei, then ratio of number of nuclei of X_(1) to X_(2) will be (1)/(e^(2)) after a time

Two radioactive materials X_(1) and X_(2) have decay constant 11 lambda and lambda respectively. If initially they have same number of nuclei, then ratio of number of nuclei of X_(1) to X_(2) will be (1)/(e^(2)) after a time

Two radioactive materials X_(1) and X_(2) have decay constant 11 lambda and lambda respectively. If initially they have same number of nuclei, then ratio of number of nuclei of X_(1) to X_(2) will be (1)/(e) after a time

Two radioactive materials A and B have decay constants 10lambda and lambda , respectively. If initially they have the same number of nuclei, then the ratio of the number of nuclei of A of that of B will be 1//e after a time :

The radioactive materials X_1 and X_2 have decay constants 5lambda and lambda respectively. If intially they have the same number of nuclei, then the ratio of number of nuclei of X_1 to that of X_2 will be 1/e

Two radiactive material A_(1) and A_(2) have decay constants of 10 lambda_(0) and lambda_(0) . If initially they have same number of nyclei, the ratio of number of their undecayed nuclei will be (1//e) after a time

Two radiactive material A_(1) and A_(2) have decay constants of 10 lambda_(0) and lambda_(0) . If initially they have same number of nyclei, the ratio of number of their undecayed nuclei will be (1/e) after a time

Two radiactive material A_(1) and A_(2) have decay constants of 10 lambda_(0) and lambda_(0) . If initially they have same number of nyclei, the ratio of number of their undecayed nuclei will be (1//e) after a time
