The mass defect in the formation of a helium nucleus () is . What is the total binding energy of the helium nucleus? ()
Answer and explanation
Correct answer: B.
- Step 1: Total nuclear binding energy is calculated using Einstein's mass-energy relation: .
- Step 2: Compute: .
Answer
.
Why not the others: is the binding energy per nucleon (); doubles the binding energy; and divides by 2.
