QJEEM22Ph07b6: JEE Main 2022 Physics - Class 12 JEEM22Ph07b6 Solution: The Q-value of a nuclear reaction and kinetic energy of the…

The Q-value of a nuclear reaction and kinetic energy of the projectile particle, Kp are related as :

Multiple Choice Options

  • A Q = Kp
  • B (Kp + Q) < 0
  • C Q < Kp
  • D (Kp + Q) > 0

Step-by-Step Verified Solution

Kp > 0

If Q is released ⇒ Q > 0

⇒ Kp + Q > 0

Even the particle has to be given kinetic energy greater than magnitude of Q to maintain momentum conservation.

⇒ K + Q > 0
