The energy equivalent of 5 g of substance is |
$2.8 × 10^{33} eV$ $4.6 × 10^{32} eV$ $2.8 × 10^{32} eV$ $5.6 × 10^{16} eV$ |
$2.8 × 10^{33} eV$ |
The correct answer is Option (1) - $2.8 × 10^{33} eV$ The energy equivalent of corresponding to an amount of mass (Δm) of a substance is given as - $E=Δmc^2$ Mass = $5g = 5 × 10^{-3}kg$ Speed of light = $3× 10^{8}m/s$ $E=4.5× 10^{12}J$ $≃2.8× 10^{33} eV$ |
