Question

The average energy released per fission of ${}_{92}^{235}U$ is :

• A. $200$ eV
• B. $200$ MeV
• C. $200$ meV
• D. $200$ GeV

Answer 1

The correct option is B $200$ MeV

The average energy released per fission of ${}^{235}U$ is $200MeV$ with emission of fission products ${}^{144}Ba$ and ${}^{90}Kr$.

This energy is equal to $3.2\times {10}^{-11}J$. This is huge amount of energy and hence fission energy is considered to be very dominant source of production of energy.
