An electron and a positron, each moving at3.0
An electron and a positron are moving toward each other and each has speed 0.420 c in the lab frame. What is the kinetic energy of each particle? in J The e+ and e− meet head-on and annihilate. What is the energy of each photon that is produced? in J What is the wavelength of each photon? in meters
An electron and a positron, each moving at 3.0 x 10^5m/s, collide head on, disappear, and produce two photons moving in opposite directions, each with the same energy and momentum. Determine the energy and momentum of each photon (show your units)
A positron is the antiparticle of the electron. Suppose an electron and a positron collide and annihilate each other. How much energy is released? The electron and positron each have a mass of 9.1 x 10-31 kg.
An electron and a positron each have a mass of 9.11 ×
10-31 kg. They collide and both vanish, with only
electromagnetic radiation appearing after the collision. If each
particle is moving at a speed of 0.42c relative to the
laboratory before the collision, determine the energy of the
electromagnetic radiation.

Problem 4. Electron-positron production An electron-positron pair (positron is electron’s antiparticle, it has the same mass as electron, but opposite charge) can be produced what two photon are collided.

An electron (rest mass me) of
energy E makes a head-on collision with a positron (positron is
electron’s antiparticle, it has the same mass as electron, but
opposite charge) In collision the two particles annihilate each
other and are replaces by two photons (γ rays) of equal energy,
each traveling at equal angles θ with electron’s direction of
motion. Find 1. The energy of each photon. 2. The momentum p of
each photon. 3. The angle θ.
