8 8. $\beta$-particles are:
Correct Answer: B
Explanation: $\beta$-particles are high-energy electrons ($-e$ charge).
9 9. The $\beta$-particles have erratic path due to their:
Correct Answer: C
Explanation: Light mass leads to frequent collisions and zigzag paths.
10 10. The penetration power of $\beta$-particles is greater than $\alpha$-particles due to their:
Correct Answer: A
Explanation: Lower ionization power allows deeper penetration.

Correct Answer: D
Explanation: Gamma rays are high-energy, neutral, and highly penetrating.
12 12. The penetrating power of $\gamma$-rays is:
Correct Answer: A
Explanation: $\gamma$-rays penetrate much farther than $\alpha$ or $\beta$ particles.
13 13. The penetrating power of $\beta$-particles is:
Correct Answer: B
Explanation: $\beta$-particles penetrate ~100x farther than $\alpha$-particles.
14 14. Which of the following radiations are highly penetrating:
Correct Answer: C
