The correct Answer is:
To solve the assertion and reason question, we will analyze both the assertion and the reason step by step. ### Step 1: Understand the Assertion The assertion states that quark particles have fractional electronic charges, but the quantum of charge is still the electronic charge (e). - **Explanation**: Quarks are fundamental particles that combine to form protons and neutrons. While quarks can have charges of +2/3e or -1/3e, the total charge of composite particles (like protons and neutrons) is an integer multiple of the elementary charge (e). ### Step 2: Understand the Reason The reason provided states that quark particles do not exist in a free state. - **Explanation**: Quarks are never found alone in nature; they are always confined within larger particles called hadrons (like protons and neutrons). This confinement is due to the strong force, which prevents quarks from existing independently. ### Step 3: Analyze the Relationship Now we need to determine if the reason correctly explains the assertion. - The assertion is true: Quarks do have fractional charges, but the total charge of observable particles is an integer multiple of e. - The reason is also true: Quarks cannot exist freely; they are always found in combinations. ### Step 4: Conclusion Since both the assertion and reason are true, and the reason correctly explains the assertion, we conclude that the answer is that both statements are true, and the reason is a correct explanation for the assertion. ### Final Answer Both the assertion and reason are true, and the reason is a correct explanation for the assertion. ---
