I found (2).
Using [tex]E=m c^{2} =9.11* 10^{-31}* (3*10^{8} )^{2} =8.2* 10^{-14}J [/tex]

Answer:

The correct answer is option 2,

The total energy released is [tex]8.20 * 10^{-14} J\\[/tex]

Explanation:

As per Einstein theory of relativity,

[tex]E = mc^2\\[/tex]

where

"E" is the energy produced by mass conversion

"m" is the mass converted

"c" speed of light

Substituting the given values in above equation we get -

[tex]E = (9.11 * 10^{-31}) Kg * ( 3 * 10^{8} \frac{m}{s} )^2\\= 8.20 * 10^{-14} J\\[/tex]
