📘 Nuclei | Nuclear Force, Binding Energy & Mass Defect | Class 12 Physics
In this video, we study the most important concepts of the chapter Nuclei from Class 12 Physics, which explain the stability of atomic nuclei. These topics are highly important for CBSE board exams, NEET, and JEE.
🔹 Topics covered in this video:
✅ Nuclear Force
Force responsible for binding protons and neutrons inside the nucleus
Properties: very strong, short-range, charge independent
Comparison with gravitational and electrostatic forces
✅ Mass Defect
Difference between the actual mass of the nucleus and the sum of masses of individual nucleons
Physical meaning of mass defect
Role of mass defect in nuclear binding
✅ Binding Energy
Relation between mass defect and binding energy (Einstein’s mass–energy relation)
Binding energy per nucleon
Stability of nuclei based on binding energy
Importance of binding energy curve (conceptual understanding)
✨ The concepts are explained in a simple, step-by-step manner, strictly based on NCERT, to help students understand theory and solve numericals confidently.
👨🎓 Useful for:
✔ Class 12 CBSE students
✔ NEET & JEE aspirants
