Question:
Which of the following statements are correct about canal rays?
• [(i)] They carry positively charged particles.
• [(ii)] The mass of the particles of these rays does not depend upon the gas present in the cathode ray tube.
• [(iii)] The particles behave in a different manner in electric field as those of cathode rays.
• [(iv)] The charge to mass ratio of the particles does not depends on the gas present in the cathode ray tube.

The Correct Option is
Solution and Explanation
Concept:
Canal rays (anode rays) consist of positively charged ions.
Step 1: Check statements.
• (i) True → positively charged particles
• (ii) False → mass depends on gas used
• (iii) True → behavior differs from cathode rays
• (iv) False → \( \frac{e}{m} \) depends on gas
Step 2: Select correct combination.
\[ (i) \text{ and } (iii) \]
