Question

The Q-value of a nuclear reaction and kinetic energy of the projectile particle, K_P are related as ______.

Options

• Q = K_p

• (K_p + Q) < 0

• Q < K_p

• (K_p + Q) > 0

Answer 1

The Q-value of a nuclear reaction and kinetic energy of the projectile particle, K_P are related as (K_p + Q) > 0.

Explanation:

We have x + p = γ + b

So, Q = K_γ + K_b - K_p

Q + K_p = K_γ + K_b 

As, K_γ + K_b > 0

So, Q + K_p > 0
