प्रश्न
The approximate value of the velocity of light in vacuum used in the mass-energy equivalence relation is:
पर्याय
\[c \approx 3 \times 10^{10} \text{ m s}^{-1}\]
\[c \approx 3 \times 10^6 \text{ m s}^{-1}\]
\[c \approx 9 \times 10^{16} \text{ m s}^{-1}\]
\[c \approx 3 \times 10^8 \text{ m s}^{-1}\]

उत्तर
The velocity of light in vacuum is approximately \[3 \times 10^8 \text{ m s}^{-1}\]. Squaring this value in \[E = mc^2\] gives the very large factor \[9 \times 10^{16}\], which multiplies the mass to yield its energy equivalent.
