Let binding energy per nucleon of nucleus is denoted by `underset(bn)(E)` and radius is denoted as r. If mass number of nuclei A,B are 64 and 125 respectively , then

Text Solution

Verified by Experts

The correct Answer is:
D
r = `r_(0)(A)^(1/3)`
r increases with increasing A mass number.
So, `r_(A)`lt`r_(B)` as mass number of A is smaller `E_(bn)` decreases with increasing A for `A gt 56^(56)`Fe has highest `E_(bn)` value.
So, `E_(bn)` for A = 64 is larger as compared to `E_(bn)` for nucleus with A = 125
`E_(bnAgtE_(bnB)`
