Answer:
3.42e+58J
Explanation:
Energy E=mc^2
C=speed of light=3*10^8
m=mass
Note that each planet contains 10^11 masses of the sun.
Energy released = (10^11*1.9*10^30)*(3*10^8)^2
Therefore, Energy released by the matter=1.71*10^58
And the energy released by the antimatter is also 1.71*10^58
Therefore total energy released by both matter and antimatter= (1.71+1.71)*10^58
=3.42e+58J
