Question

In a fission process, nucleus $A$ divides into two nuclei $B$ and $C$, their binding energies being $E_a,E_b$ and $E_c$ respectively. Then

• A. $E_b+E_c=E_a$
• B. $E_b+E_c>E_a$
• C. $E_b+E_c<E_a$
• D. $E_b.E_c=E_a$

Answer 1

The correct option is B $E_b+E_c>E_a$

The release of energy is possible when the binding energy of the products is greater than the binding energy of the reactants.

As it is a fission process, there will be release of energy,

Therefore, the binding energy of the products will be greater than the binding energy of the reactants.

$E_b+E_c>E_a$

Hence, option $\left(B\right)$ is correct.
