The energy associated with the anihilation of the electron and the positron is 1.638 * 10^-13 J.

What is anihilation of matter?

Matter is anihilted when it collides with its antimatter. We know that the positron is the antimatter of the electron. Now, we have the total mass of the system as; 2(9.109 x 10^-31 Kg) = 1.82 * 10^-30 Kg

Using the Eienstein relation;

E= mc^2

E = 1.82 * 10^-30 Kg (3 * 10^8)^2

E = 1.638 * 10^-13 J
