    Starting with a sample of pure \[\frac{\phi }{3}\], 7/8 of it decays into Zn in 15 min. The corresponding half-life is

    A)  10 min                                 

    B)  15 min                 

    C)  5 min                                   

    D)  \[\frac{q}{{{\varepsilon }_{0}}}-\phi \] min

    Correct Answer: C

    Solution :

    \[{{\mu }_{s}}=\sqrt{1-\frac{1}{{{n}^{2}}}}\] \[{{R}^{2}}\]  \[\frac{1}{{{R}^{2}}}\] \[\frac{1}{R}\]  \[R\] \[f\]   \[f\] \[s=\frac{1}{6}f{{t}^{2}}\]  \[3\ln \,2=\lambda t\] \[s=\frac{1}{4}f{{t}^{2}}\]   \[\left( \frac{ch\arg e\,on\,the\,ion}{mass\,of\,the\,ion} \right)\] Half-life period \[\frac{1}{R}\] \[\frac{1}{{{R}^{2}}}\]
