A) T = 0.693 t
B) t = 0.693 T
C) t = t
D) t = 2.718 T
Correct Answer: A
Solution :
The average of the life of the nuclei is called average life\[\tau \]. The average life of radioactive material is equal to the reciprocal of the decay constant X, ie, \[\tau =\frac{1}{\lambda }\] But \[T=\frac{0.693}{\lambda }\] \[\therefore \] \[T=0.693\,\tau \]You need to login to perform this action.
