A proton and an antiproton each with total energy of 400 GeV collide head-on. What is the total energy (particles + energy) released?
A) zero
B) 400 Gev
C) 800 GeV
D) 1 600 GeV
E) 2 400 GeV

Question

Quizplus · Accepted Answer

When a proton and an antiproton collide, they annihilate each other, creating pure energy in the form of photons. The total energy released is equal to the sum of the total energy of the proton and antiproton, which is 800 GeV. Therefore, the correct option is (C) 800 GeV.
