Half life of a radio-active element is 8 years, how much amount will be present after 32 years?

Options:

Answer:

Solution:

Here, $T_{1/2} = 8$ years $t = 32$ years Using, $N = N_{0} (\frac{1}{2})^{\frac{t}{T _{1/2}}}$ $(\frac{℧ _{0}}{℧ _{0}}) = (\frac{1}{2})^{\frac{32}{8}} = (\frac{1}{2})^{4}$ $(\frac{\approx}{\nabla _{0}}) = \frac{1}{16}$
