Question

The charge on positron is equal to the charge on ?

• A. proton
• B. electron
• C. nucleon
• D. neutron

Answer 1

Answer:

A. proton

Charge on a positron is equal to that of proton.The positron or antielectron is the antiparticle or the antimatter counterpart of the electron. The positron has an electric charge of +1e, a spin of, and has the same mass as an electron. When a low-energy positron collides with a low-energy electron, annihilation occurs, resulting in the production of two or more gamma ray photons.
