The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Assertion (A):** The assertion states that the charge to mass ratio of anode rays depends on the nature of the gas taken in the discharge tube. - **Explanation:** Anode rays are produced when a high voltage is applied to a gas in a discharge tube. This causes the gas atoms to ionize, resulting in the formation of positive ions (anode rays) and electrons (cathode rays). The specific type of gas used will determine the types of ions produced, which in turn affects their charge and mass. **Hint:** Consider how different gases ionize and the types of ions they produce. 2. **Understanding the Reason (R):** The reason states that the particles of anode rays carry a positive charge. - **Explanation:** This statement is true. Anode rays consist of positively charged particles (ions) that are created when the gas atoms lose electrons during ionization. **Hint:** Recall the definition of anode rays and their composition. 3. **Evaluating the Relationship between A and R:** We need to determine if the reason (R) is a correct explanation for the assertion (A). - **Analysis:** While both statements are true, the reason does not explain why the charge to mass ratio depends on the nature of the gas. The charge to mass ratio depends on the specific ions produced, which varies with different gases, not merely because the particles are positively charged. **Hint:** Think about whether the positive charge alone is sufficient to explain the dependency on gas type. 4. **Conclusion:** Both the assertion (A) and the reason (R) are correct statements, but the reason is not the correct explanation of the assertion. Therefore, the correct answer is that both statements are true, but R is not the correct explanation for A. **Final Answer:** Both A and R are correct, but R is not the correct explanation for A. ---

Assertion : The characteristics of cathode rays do not depend upon the material of electrodes and the nature of the gas present in the cathode ray tube. Reason : Cathode rays consist of negatively charged particles, called electrons.

A subatomic particle that carries a negative charge

The existence of negatively charged particle in an atom was shown by J.J. Thomson as a result of the studies of the passage of electricity through gases at extremely low pressure known as discharge tube experiments. When a high voltage of the order of 10,000 volts or more was impressed across the electrodes, some sort of invisible rays moved from the negative electrode to the positive electrode these rays are called as cathode rays. Cathode rays travel in straight path in absence of electrical and magnetic field . Cathode rays consist of material part and charged particles? Cathode rays produce X-rays and light is emitted when they strike on ZnS screen. Cathode rays penetrate through thin sheets of aluminium and other metals . They affect the photogenic plate and passes heating effect when they strike on metal foil. The raito of charge to mass i.e charge/mass is same for all the cathode rays irrespective of the gas used in the tube. The existence of positively charged particle in an atom was shown be E. Goldstein. He repeated the same discharge tube experiments by using a perforated cathode. It was observed that when a high potential difference was applied between the electrodes, not only cathode rays were produced but also a new type of rays were produced simultaneoulsy from anode moving towards cathode and passes through the holes or canal of the cathode. These termed as canal rays or anode rays. These rays travel in straight lines and consists of positively charged particles. These rays have kinetic energy and produces heating effect also. The e/m ratio of these rays is smaller than that of electrons. Unlike cathode rays, their e/m value is dependent upon the nature of the gas taken in the tube. These rays produced flashes of light on ZnS screen and can pass throughs thin metal foils. They can produce physical and chemical changes and are capable to produce ionisation in gases. Which is not true with respect to cathode rays?
