TS EAMCET 7 May 2018 Shift 1 Solved Paper

Consider a radioactive nuclide which follow decay rate given by A (t) = A02(t∕t0) , where A (t) is the fraction of radioactive material remaining after time 't' from the initial A0 at zero time. Let A1 be the fraction of original activity which remains after 120 hours. Likewise A2 is the fraction of original activity remaining after 200 hours. If

A1

A2

= 16 , then the half-life (t0) will be
