In problem` 43`, number of atoms decayed between time interval `t_(1)`

1.	In problem` 43`, number of atoms decayed between time interval `t_(1)` and `t_(2)` areA. `(ln(2))/(lambda) (R_(1) R_(2))`B. `R_(1) e^(-lambda t_(2)) -R_(2) e^(-lambda t_(2))`C. `lambda(R_(1)-R_(2))`D. `(R_(1)-R_(2))/(lambda))`
Answer» Correct Answer - d `R_(1) =lambdaN_(1) rArr N_(1) =(R_(1))/(lambda)` and `R_(2) =lambdaN_(2)rArr N_(2) =(R_(2))/(lambda)` Therefore, number of atoms decayed `=N_(1)-N_(2) =((R_(1)-R_(2))/(lambda))`.
