Question

Nucleus X has A = 40 and total binding energy 336 MeV. Nucleus Y has A = 56 and total binding energy 492.8 MeV. Nucleus Z has A = 240 and total binding energy 1824 MeV. Which statements are correct?

G1 Physics · Accepted Answer

For X: BE ÷ A = 336 ÷ 40 = 8.4 MeV per nucleon. So A is correct. For Y: BE ÷ A = 492.8 ÷ 56 = 8.8 MeV per nucleon. So B is correct. For Z: BE ÷ A = 1824 ÷ 240 = 7.6 MeV per nucleon. So C is correct. The greatest value is 8.8 MeV for Y, not Z. Therefore D is false. Correct answers: A, B and C.
