Question

What is the minimum total energy released when
an electron and its antiparticle (positron)
annihilate each other?

Answer 1

let m be mass of electron,
then positron being antiparticle of electron ... has same mass --- 'm'

And we have Einstein's mass energy realtion E = mc^2 where c is velocity of light.

And put this type of question on physics section!!

Answer 2

oh wow! i didn't know i was in the wrong section! >< sorry!
