List of top Physics Questions on Nuclear fission

Assertion : Energy is released when heavy nuclei undergo fission or light nuclei undergo fusion.
Reason (R): For heavy nuclei, binding energy per nucleon increases with increasing \( Z \) while for light nuclei, it decreases with increasing \( Z \).
What is the energy released by 1 gram of natural Uranium, assuming 200 MeV is released in each fission event and the reasonable isotope \(^{235}\mathrm{U}\) has an abundance of 0.7% by weight in natural Uranium? Choose the correct answer. (Take Avogadro's number, \(N_A = 6.022 \times 10^{23}\ \text{mole}^{-1}\)):
