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?

Answer»

`M_(2) gt 2M_(1)`
`M_(2) lt 20 (m_(p)+m_(n))`
`M_(2)=2M_(1)`
`M_(2) lt 2M_(1)`

Solution :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)
