If `m_(p)` is the mass of proton. `m_(n)` that of a neutron, `M_(1)` that of `_(10)Ne^(20)` nucleus and `M_(2)` that of `_(20)Ca^(40)` nucleus, then which of the following relations is//are not true?
A. `M_(2) gt 2M_(1)`
B. `M_(2) lt 20 (m_(p)+m_(n))`
C. `M_(2)=2M_(1)`
D. `M_(2) lt 2M_(1)`

Correct Answer - A, C
More the nucleons, more the more the binding energy & more reduced is the mas. So, `M_(2) lt 20(m_(p)+m_(n))` (Because some mass got reduced on release of binding energy).
`M_(2) lt 2M_(1)` (Because more mass is reduced for binding more nucleons)
