(a) Write Einstein's mass-energy equation. Give the meaning of each symbol which occurs in it.
(b) If 25 atomic mass units (u) of a radioactive material are destroyed in a nuclear reaction, how much energy is released in MeV?
(a) Einstein's mass-energy equation is given as follows:
E = mc2
Where, E is the amount of energy produced if mass, m is destroyed and c is the speed of light in vacuum.
(b) If 25 atomic mass units (u) of a radioactive material are destroyed in a nuclear reaction, then the amount of energy released in MeV is given by:
$25\times 931=23275MeV$ (since 1 u = 931 MeV)
23275 MeV of energy is released.
