    Sulphur-35  (34.96903  amu) emits a P-particle but no \[\gamma -\] ray. The product is chlorine-35 (34.96885 amu). The maximum energy of the \[\beta -\] particle emitted is :

    A)  1.6758 MeV      

    B)  16.758 MeV

    C)  0.016758 MeV                 

    D)  0.16758 MeV

    Correct Answer: D

    Solution :

                     Energy can be calculated by calculating the value of mass defect. \[\Delta m=34.96903-34.96885\] \[=0.00018\,\text{amu}\text{.}\] Maximum energy \[dE=\Delta m\times 931.5\,\text{Me}\,\text{V}\] \[=0.00018\times 931.5\] \[=0.16758\,\text{MeV}\]
