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

A

`3.2 xx 10^(-13)J`

B

`1.6 xx 10^(-13)J`

C

`4.8 xx 10^(-13)J`

D

`6.4 xx 10^(-13)J`

Text Solution

Verified by Experts

The correct Answer is:
B

`Dleta M= 2m = 2 xx 9 xx 10^(-31) kg`
`E= Delta M xx c^(2)`
`=18 xx 10^(-31) xx (3 xx 10^(8))^(2)= 1.6 xx 10^(-13)J`

An electron - positron pair annihilates at rest to produce gamma -rays. Calculate the energy produced in MeV if the rest mass of electron is 9.1xx10^(-31)kg .

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

A gamma ray photon creates an electron-positron pair. If the rest mass energy of an electron is 0.5 MeV and the total K.E. of the electron-position pair is 0.78 MeV , then the energy of the gamma ray photon must be.

The positron is a fundamental particle with the same mass as that of the electron and with a charge equal to that of an electron but of opposite sign. When a positron and an electron collide, they may annihilate each other. The energy corresponding to their mass appears in two photons of equal energy. Find the wavelength of the radiation emitted.
