Chapter 20, Problem 41R

To determine

The effect on the motion of an alpha particle and gamma particle when it is passed between a positively and negatively charged electrodes.

Explanation of Solution

Alpha particles are positively charged particles carry 2-unit positive charges. Alpha particles consist of two protons and two neutrons tightly bound together.

Gamma particles are one kind of energy having no charge. These are high penetrating particles, having ionizing ability is zero and move with the speed of light.

Conclusion:

Alpha particles are deflected from positively charged electrode.

Alpha particles are attracted by negatively charge electrode.

Gamma rays are kind of energy which never be affected by any electrode.
