When an electron collides with a positron the two particles
A) fuse to form a heavier particle
B) bounce off each other
C) are destroyed, producing a pair of high-energy gamma rays
D) are destroyed, producing another pair of particles

Question

Quizplus · Accepted Answer

This is because the electron and positron have opposite charges but equal mass, so their collision results in the complete destruction of both particles and the release of energy in the form of the gamma rays.
