Answer 2

Answer:

None of the given option are correct  ,  energy is obtained by annihilation of 1 gm of matter is  9 × $10^{13}$  J .

Explanation:

Given , mass = 1gm = $10^{-3}$ kg

We know that,

(E) = m × $c^{2}$

where E  stand for energy , m stand for mass and c is  the speed of light

And the value of c =   3 ×$10^{8} m^{2} /s^{2}$ .

So , from the  energy formula we get

E = m$c^{2}$

⇒E = $10^{-3}$ ×$(3 . 10 ^{8 } )^{2}$

⇒E = 9 × $10^{-3} . 10^{16}$

⇒E = 9 × $10^{13}$J

Hence ,  9 × $10^{13}$ joule of energy  is obtained by annihilation  of 1 gm of matter.
