A radioactive nucleus has a decay constant \(\lambda\) and its radioactive daughter nucleus has a decay constant 10\(\lambda\). At time t = 0, N0 is the number of parent nuclei and there are no daughter nuclei present. N1(t) and N2(t) are the number of parent and daughter nuclei present at time t, respectively The ratio \(\frac{N_2(t)}{N_1(t)}\) is
