Destruction of e-p pair:energy?

In summary, the amount of energy released when a+q and a-q charges coalesce together depends on their initial separation and size. If they are initially at rest, then the total energy released is equal to twice the rest mass of the two particles. This process is known as annihilation and results in the neutralization of the charges and the disappearance of the electric field.

When a+q & a-q charges colesce together, the neutralization collapses the charge configuration & the electric field is gone.what is the amount of energy released?

It depends on how far apart they end up and how big (diameter) they are! What is the amount of work done by the charges in moving from infinity separation to the final state?

The language you are using is not standard but I am assuming you are taking about an *annihilation* process (liek an electron-positron annihilation, say).

Well, energy is conserved. So the total energy released is simply the sum of the energies of the two particle annihilating (using the relativistic expression [itex] E = \gamma mc^2 [/itex]). *If* the two particles are initially at rest, then the energy released is 2mc^2 (notice that a particle and its antiparticle always have the same rest mass).
 

FAQ: Destruction of e-p pair:energy?

What is the "destruction of e-p pair:energy"?

The destruction of e-p pair:energy refers to the process in which an electron-positron pair (e-p pair) annihilates and releases energy in the form of photons. This can occur in high-energy collisions or in the presence of strong electromagnetic fields.

How is energy released during the destruction of e-p pair?

When an electron and positron collide, they can annihilate each other and produce two photons with equal energy. This energy is released in the form of electromagnetic radiation.

Can the destruction of e-p pair:energy be reversed?

No, the destruction of e-p pair:energy is an irreversible process. Once the e-p pair has been annihilated, the energy is released and cannot be reversed.

What factors affect the energy released during the destruction of e-p pair?

The energy released during the destruction of e-p pair is affected by the mass of the particles, their speed, and the strength of the electromagnetic field. A higher mass and speed result in more energy being released, while a stronger field can increase the chances of an e-p pair annihilating.

What are the applications of the destruction of e-p pair:energy?

The destruction of e-p pair:energy has various applications in fields such as particle physics, nuclear energy, and medical imaging. It is also used in positron emission tomography (PET) scans to produce images of the body's internal structures.
