Energy of 1g uranium is equal to.

A

9.0×1013J9.0 \times 10^{13}J

B

9.0×1019J9.0 \times 10^{19}J

C

3.0×1016J3.0 \times 10^{16}J

D

3.0×1017J3.0 \times 10^{17}J

Answer

9.0×1013J9.0 \times 10^{13}J

Explanation

Solution

E=mc2=(1×10−3)(3×108)2=9×1013JE = mc^{2} = (1 \times 10^{- 3})(3 \times 10^{8})^{2} = 9 \times 10^{13}J.
