A positron is a particle similar to an electron, but with the opposite charge of an electron. If a positron and an electron collide, sometimes both the electron and positron disappear, and two photons are created. This is an example of A positron is a particle similar to an electron, but with the opposite charge of an electron. If a positron and an electron collide, sometimes both the electron and positron disappear, and two photons are created. This is an example of potential energy: a. being converted into thermal energy.
b. rest-mass energy being converted into kinetic energy.
c. kinetic energy being converted into rest-mass energy.
d. rest-mass energy being converted into radiative energy.
