JEE MAIN - Physics (2022 - 28th June Morning Shift - No. 15)
The Q-value of a nuclear reaction and kinetic energy of the projectile particle, Kp are related as :
Q = Kp
(Kp + Q) < 0
Q < Kp
(Kp + Q) > 0
Penjelasan
Kp > 0
If Q is released $$\Rightarrow$$ Q > 0
$$\Rightarrow$$ Kp + Q > 0
Even the particle has to be given kinetic energy greater than magnitude of Q to maintain momentum conservation.
$$\Rightarrow$$ K + Q > 0
