In annihilation process particles move in:
Correct answer: B. Opposite direction
- A. Same direction
- B. Opposite direction
- C. Perpendicular position
- D. Remain stationary
Explanation
Annihilation refers to a process in which a particle and its corresponding antiparticle come into contact and mutually annihilate, resulting in the production of other particles or energy.In annihilation, a particle and an antiparticle with opposite charges and other quantum numbers (such as lepton number or baryon number) can annihilate each other upon collision.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
