QAIPM-2001-Ph-2916: NEET 2001 Physics - Class 12 AIPM-2001-Ph-2916 Solution: \(M_n\) and \(M_p\) represent the mass of neutron and proton…

MnM_n and MpM_p represent the mass of neutron and proton respectively. An element having mass M has N neutrons and Z protons, then the correct relation will be

Multiple Choice Options

  • A M<{N⋅Mn+Z⋅Mp}M<\{N\cdot M_n+Z\cdot M_p\}
  • B M>{N⋅Mn+Z⋅Mp}M>\{N\cdot M_n+Z\cdot M_p\}
  • C M={N⋅Mn+Z⋅Mp}M=\{N\cdot M_n+Z\cdot M_p\}
  • D M=N{Mn+Mp}M=N\{M_n+M_p\}

Step-by-Step Verified Solution

Given : Mass of neutron = M n Mass of proton = M p ; Atomic mass of the element = M ; Number of neutrons in the element = N and number of protons in the element = Z. We know that the atomic mass (M) of any stable nucleus is always less than the sum of the masses of the constituent particles. Therefore, M < [NM n + ZM p ]. X is a neutrino, when b-particle is emitted.
