Calculate the amount of energy released when a radioactive substance undergoes fusion and results in a mass defect of 2 kg. |
|
Answer» Solution :MASS defect in the reaction (m) = 2 kg Velocity of light (c)= `3 xx 10^(8)ms^(-1)` By Einstein.s EQUATION, Energy released `E= mc^(2)` So `E= 2 xx ( 3 xx 10^(8))^(2)` `= 1.8 xx 10^(17)J` |
