PhysicsSingle correct+4 / -1Question 45 of 90

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

Q=K_p

(K_p+Q)<0

Q<K_p

(K_p+Q)>0

Answer and worked solution

Official answer: D

Energy balance. The products carry kinetic energy $K_p+Q$ , which must be positive for the reaction to occur.

(D)

Topics:Mass defect and binding energy
