if an electron and a positron annihilitate , them the energy relasesed is

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

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

The rest mass of an electron as well as that of positron is 0.51 MeV. When an electron and positron are annihilate, they produce gamma-rays of wavelength(s)

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

The rest mass of an electron as well as that of positron is 0.51 MeV. When an electron and positron are annihilate, they produce gamma-rays of wavelength(s)

A 1 MeV positron encounters a 1 MeV electron travelling in opposite direction. The total energy released is (In MeV )

The positronium consisting of an electron and a positron corresponding binding energy and wavelength of first line in Lyman series of such a system.
