Annihilation

Description:

Annihilation gives a proof of conservation of charges. This can be observed during atom bomb reaction i.e nuclear fission reaction in which one positron and one electron strikes together and produces a lot of energy.

These particles (electron and positron) strikes because they contain opposite charges and we know that opposite charges always exerts force of attraction. This force creates acceleration on charges, due to which speed increases million times when distance is very small and which results in collision. In this collision the particles get destroyed or both electron and positron annihilates each other releasing a lot of energy in form of Electromagnetic wave i.e Y (Gama rays).

Annihilation is the process where one electron and one position collide, both are destroyed and convert to energy.

In this process, the charge remains 0 again.

Example −

Note − Y rays contains no charges because Electron and positron both annihilates each other and hence satisfies the law of conservation of charges.
