The correct Answer is:
To solve the assertion and reason question regarding surface tension, we will analyze both statements step by step. ### Step 1: Analyze the Assertion **Assertion:** Surface tension `(T = F/l)` is not a vector quantity. - **Explanation:** Surface tension is defined as the force per unit length acting along the surface of a liquid. It is a measure of the cohesive forces acting at the surface of a liquid. While it has a direction (acting along the surface), it does not satisfy the vector laws of addition, which means it cannot be treated as a vector quantity in the same way that forces can. Therefore, the assertion is **true**. ### Step 2: Analyze the Reason **Reason:** Direction of force is specified. - **Explanation:** The reason states that the direction of the force is specified. In the context of surface tension, the force does indeed have a specified direction, which is perpendicular to the surface of the liquid. However, just having a specified direction does not necessarily make a quantity a vector. For a quantity to be classified as a vector, it must satisfy the vector laws of addition, which surface tension does not. Thus, the reason is also **true**, but it does not correctly explain why surface tension is not a vector quantity. ### Step 3: Conclusion - Both the assertion and the reason are true, but the reason does not provide a correct explanation for the assertion. Therefore, the correct option is that both statements are true, but the reason is not the correct explanation for the assertion. ### Final Answer: - Assertion is true, Reason is true, but Reason is not the correct explanation for Assertion. ---
