If Nt = Noe – λt then number of disintegrated atoms between t1 to t2 ( t2 > t1) will be :–
- No \(\left[e^{\lambda t_{2}}-e^{\lambda t_{1}}\right]\)
- No\(\left[e^{\lambda t_{2}}-e^{\lambda t_{1}}\right]\)
- No \(\left[e^{-\lambda t_{1}}-e^{\lambda t_{2}}\right]\)
- None of these
Answer
(C) N o [e^ - t_ 1 -e^ t_ 2 ]
