Question

16. In, annihilation process in which an
electron and a positron transform into
gamma rays, which property of electric
Charge is displayed a. Additivity of charge
b. Quantisation of charge
c.conservation of charge
d.Attraction and repulsion​

Answer 1

Explanation:

According to the law of conservation of energy, their masses are converted to two annihilation gamma photons with an energy of around 511 keV and moving in two opposite directions. Where e− is the electron, e+ is the positron and γ are gamma rays emitted.

Answer 2

In, annihilation process in which an electron and a positron transform into gamma rays, C) conservation of charge is a property in which electric charge is displayed.

Explanation:

• Annihilation is the process that occurs when a subatomic particle collides with its respective antiparticle to produce other particles, such as an electron colliding with a positron to produce two photons.
• When an electron and a positron collide, they annihilate and disappear, giving off two gamma-rays in the process.
• The particles appear to have vanished and all energy is transferred to the gamma rays.
• When a positron and an electron collide, they are annihilated and two gamma photons of equal energy are emitted.
