Interpretation: To determine the binding energy of the
Concept introduction:Mass defect:
The nucleus of each atom (aside from
Mass and energy are related by following equation.
E = Energy
M = mass
C =
Calculated mass of nucleus:
The calculated mass of nucleus is equal to the sum of masses of its protons and neutrons.
mH = mass of proton
mn= mass of neutron.
Loss of mass and liberation of energy are related by Einstein’s equations.
Binding energy:
The binding energy is the energy that would be needed to disassemble a nucleus into individual nucleons.
The formula of binding energy
Loss of mass and liberation of energy are related by Einstein’s equations.
Answer to Problem 14.41PAE
Solution: The binding energy of
Explanation of Solution
Given information: Experimentally determined mass of
Formula used:
where,
E= binding energy
