The energy equivalent of 5 g of substance is
Answer & explanation
Correct answer: option 1
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 = $3× 10^{8}m/s$
$E=4.5× 10^{12}J$
$≃2.8× 10^{33} eV$
