Answer :
use the famous equation due to Einstein
e = mc^2
not sure about the units if we are working in joules I think m should be in kilograms and c is the speed of light in meters / second.

Answer : The correct option is, (B) [tex]9.0\times 10^{13}J[/tex]
Explanation : Given,
Mass of matter = 1.0 g = 0.001 g
Conversion : 1 Kg = 1000 g
Formula used :
[tex]E=mc^2[/tex]
where,
E = energy of the matter = ?
m = mass of the matter = 1.0 g
c = speed of matter = [tex]3\times 10^8m/s[/tex]
Now put all the given values in this formula, we get :
[tex]E=(0.001g)\times (3\times 10^8m/s)^2[/tex]
[tex]E=9.0\times 10^{13}J[/tex]
Therefore, the energy of the matter will be, [tex]9.0\times 10^{13}J[/tex]
