AIPMT 2004

MCQ (Single Correct Answer)

-1

If M(A; Z), M_p and M_n denote the masses of the nucleus $${}_Z^AX,$$ proton and neutron respectively in units of u (1 u = 931.5 MeV/c²) and BE represents its bonding energy in MeV, then

M(A, Z) = ZM_p + (A $$-$$ Z)M_n $$-$$ BE

M(A, Z) = ZM_p + (A $$-$$ Z)M_n + BE/c²

M(A, Z) = ZM_p + (A $$-$$ Z)M_n $$-$$ BE/c²

M(A, Z) = ZM_p + (A $$-$$ Z)M_n + BE

If in a nuclear fusion process the masses of the fusing nuclei be m₁ and m₂ and the mass of the resultant nucleus be m₃, then

m₃ = m₁ + m₂

m₃ = $$\left| {{m_1} - {m_2}} \right|$$

m₃ < (m₁ + m₂)

m₃ > (m₁ + m₂)
