Compare the energy released by the collisions and annihilation of( 1) an electron and a positron and (2) a proton and an antiproton.

Question

Quizplus · Accepted Answer

The energy released in the annihilation of a proton and an antiproton is much greater than that of an electron and a positron due to the much greater mass of protons compared to electrons. According to Einstein's equation, E=mc^2, the energy released is directly proportional to the mass of the particles involved. Since protons are approximately 1836 times more massive than electrons, their annihilation releases significantly more energy.
