Physics Question on Nuclear physics

The energy equivalent of 0.5 g of a substance is:

A

4.5×1016J4.5 \times 10^{16} J

B

4.5×1013J4.5 \times 10^{13} J

C

1.5×1013J1.5 \times 10^{13} J

D

0.5×1013J0.5 \times 10^{13} J

Answer

4.5×1013J4.5 \times 10^{13} J

Explanation

Solution

From mass-energy equivalence,
E=mc2E=mc^{2}
=0.5×10−3×9×1016=0.5\times 10^{-3}\times 9\times 10^{16}
=4.5×1013 J=4.5 \times 10^{13}\,J
