Answer : 1. "पॉजिट्रान"
Explanation :

The positron is the antiparticle to the electron. The positron has the same rest mass (m0) as the electron but opposite charge, one positive elementary charge. In condensed matter, each positron annihilates with an electron yielding γ-rays in a very short time (1010–109 s).
