Destruction of e-p pair:energy?

AI Thread Summary
When a positive and negative charge pair annihilates, the neutralization collapses their charge configuration, eliminating the electric field. The energy released during this process is determined by the total energy of the particles involved, calculated using the relativistic formula E = γmc². If the particles are at rest before annihilation, the energy released is 2mc², where m is the mass of the particle. The final energy output depends on the initial separation and the resulting configuration of the particles. Understanding this annihilation process is crucial for grasping energy conservation in particle physics.

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?
Please note that it is a personal query-not homework

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 E = \gamma mc^2). *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).

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
