Subtopic: Inverting and Non-inverting Op-Amp Configurations
Question Statement:
An \alpha-particle is emitted from the decay of Americium ( Am) at rest, i.e.,
Am94
241 → U92
237 + \alpha. The rest mass es of Am94
241 , U92
237 and \alpha are 224.544
GeV/c2, 220.811 GeV/ c2 and 3.728 GeV/ c2 respectively. What is the kinetic
energy (in MeV/c2, rounded off to two decimal places) of the \alpha-particle?
Official Answer Key:
4.90 to 4.94
