Assertion : An electron and positron can annihilate each other creating a photon.
Reason: Electron and positron form a particle and anti-particle pair.

When and electron-positron pair annihilates, the energy released is about.

When and electron-positron pair annihilates, the energy released is about.

Name the anti-particle of an electron.

Calculate the energy released when an electron annihilates a positron.

An elcetron and a positron moving at small speeds collide and annihilate each other. Find the energy of the resulting gamma photon .

An elcetron and a positron moving at small speeds collide and annihilate each other. Find the energy of the resulting gamma photon .

Statement-I : Coversionof a gamma photon into an electron and a positron is an example of pair production. Statement -II : Pair production refers to the creation of an elementary particle and its antiparticle,usually when a photon interacts with a nucleus.
