Question

Properties of canal rays:

• A. They are positively charged.
• B. They are negatively charged.
• C. They travel in straight lines.
• D. They have no mass.

Hint:

Canal rays are positively charged ions that move towards the cathode in a discharge tube.

Answer 1

The Correct Option is A

Canal rays are positively charged particles that are formed when high-voltage discharge is passed through a gas at low pressure. These rays are composed of positive ions that move toward the cathode in the presence of an electric field. They are emitted from the anode and travel in straight lines unless deflected by electric and magnetic fields. Thus, the correct answer is that canal rays are positively charged.
