What would be the amount of energy released if 1 g of a substance is converted to energy? (Given, speed of light in vaccum = $3 \times 10^8 ms^{-1}$)
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → $9 \times 10^{13}J$
Energy (E) is -
$E=mc^2$
$=(1×10^{-3})×(3×10^8)^2$
$=9×10^{13}J$
