The energy equivalent of 0.5 g of a substance is:
Updated On: Apr 5, 2022
- $4.5 \times 10^{16} J$
- $4.5 \times 10^{13} J$
- $1.5 \times 10^{13} J$
- $0.5 \times 10^{13} J$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
From mass-energy equivalence,
$E=mc^{2}$
$=0.5\times 10^{-3}\times 9\times 10^{16}$
$=4.5 \times 10^{13}\,J$
