A) \[2\times {{10}^{3}}\,years\]
B) \[1.5\times {{10}^{3}}\,years\]
C) \[3\times {{10}^{3}}\,years\]
D) \[2.5\times {{10}^{3}}\,years\]
Correct Answer: C
Solution :
As half-life \[=\frac{0.693}{\lambda }\] \[=\frac{0.693}{2.31\times {{10}^{-4}}}=3\times {{10}^{3}}\,\text{years}\] Hence, the correct option is (c).You need to login to perform this action.
