Just came up with a new thought, I could create a situation such that the electron and positron are approaching each other in such a manner that initial p=0. This would allow the dismissal of the "at rest" presumption. Thoughts?
Homework Statement
The problem is listed as follows: Show that conservation of energy and momentum require at least two gamma rays to e emitted in the annihilation of an electron by a positron.
Homework Equations
p(initial) = p(final)
E(initial) = E(final)
Total rest mass = 1.0218...
Homework Statement
Hey everyone. I've been trying to figure out these two problems for a few hours now to no luck. I really have no idea where to start. Hopefully, someone can help me out.
1) a) How much time is needed to measure the kinetic energy of an electron whose speed is 10.0 m/s with...
