Question

An electron and a positron are shot directly toward each other by a particle accelerator. They start very far apart from each other, each with a kinetic energy of 5*10^(-14) J. When they collide, they disintegrate and completely transform into two photons. What is the total kinetic energy of the two photons after the collision?

Step 1

The total initial energy is the sum of the kinetic energies of the electron and positron: Ei = 2(5*10^(-14) J) = 1*10^(-13) J Show more…
