JEE MAIN - Physics (2010 - No. 4)
A nucleus of mass $$M+$$$$\Delta m$$ is at rest and decays into two daughter nuclei of equal mass $${M \over 2}$$ each. Speed of light is $$c.$$
The binding energy per nucleon for the parent nucleus is $${E_1}$$ and that for the daughter nuclei is $${E_2}.$$ Then
$${E_2} = 2{E_1}$$
$${E_1} > {E_2}$$
$${E_2} > {E_1}$$
$${E_1} = 2{E_2}$$

In nuclear fission, the binding energy per nucleon of daughter nuclei is greater than the parent nucleon of daughter nuclei is greater than the parent nucleus.
