A) 3.555 MeV
B) 3.5 MeV
C) 3.545 MeV
D) 3.045 MeV
Correct Answer: D
Solution :
Key Idea: Every subsatance has energy due to its mass also. Einstein by his theory of relativity proved that mass and energy are related to each other and every substance has energy due to its mass also. If a substance loses an amount Am of its mass, an equivalent amount \[\Delta E\] of energy is produced, according to relation \[\Delta E=\Delta m{{c}^{2}}\]where, c is speed of light. This is called Einstein's mass energy relation. \[\therefore \] Kinetic energy \[=(m-{{m}_{0}}){{c}^{2}}\] Putting the numerical value, we have \[=(3.555-0.51)MeV\] \[=3.045\,\text{MeV}\]
