Challenge Problems
Push your limits with challenges.
Question 1
Calculate the binding energy of a carbon nucleus composed of 6 protons and 6 neutrons. If the total mass of the nucleus is 12.011 u and the mass defect is 0.012 u. Use 1 u = 931.5 MeV for the energy calculation.
💡 Hint: Start with finding the mass defect and then apply it to the known conversion for energy.
Question 2
Discuss how mass-energy equivalence relates to real-life nuclear applications, such as nuclear reactors.
💡 Hint: Think about how splitting nuclei can release energy based on mass defect.
