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

A

`3.2xx10^(-13)J`

B

`1.6xx10^(-13)J`

C

`4.8xx10^(-13)J`

D

`6.4x10^(-13)J`

Text Solution

Verified by Experts

The correct Answer is:
b
Mass of electron = Mass of position `=9.1xx10^(-31)kg`
According to positron annihilation,
`""_(+)beta^(0)+""_(-)beta^(0)tohv+hv`
Energy released, `E=(2m).c^(2)`
`=2xx9.1xx10^(-31)xx(3xx10^(8))=1.6xx10^(-13)J`

A positronium consists of an electron and a positron revolving about their common centre of mass. Calculate the separation between the electron and positron in their first excited state:

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. [Take : mass of electron = (0.5//c^(2))MeV and hc = 1.2 xx 10^(-12) MeV-m , where h is the Planck's constant and c is the velocity of light in air.

Positron is the antiparticle of an electron .It has the same mass as an electron but the opposite charge An electron and a positron moving towards each other with equal and opposite velocities.

A positron of 1MeV collides with an electron of 1MeV and gets annihilated and the reaction produces two gamma- ray photons. If the effective mass of each photons is 0.0016amu, then the energy of each gamma- ray photon is about-

In an ordianary atom, as a first approximation, the motion of the nucleus can be ignored. In a positronium atom a positronreplaces the proton of hydrogen atom. The electron and positron masses are equal and , therefore , the motion of the positron cannot be ignored. One must consider the motion of both electron and positron about their center of mass. A detailed analyasis shows that formulae of Bohr's model apply to positronium atom provided that we replace m_(e) by what is known reduced mass is m_(e)//2 .
