Mass Defect & Binding Energy

The energy equivalent of 0.5 g of a substance is:

Show answer and solution

Answer: (a)

  1. E=mc2=(0.5×10−3)(3×108)2E = mc^2 = (0.5 \times 10^{-3})(3 \times 10^8)^2
  2. E=0.5×10−3×9×1016=4.5×1013 JE = 0.5 \times 10^{-3} \times 9 \times 10^{16} = 4.5 \times 10^{13}\ \text{J}
  3. So the answer is (a) 4.5×10134.5 \times 10^{13} J.
