The correct Answer is:
To analyze the given statements, we will break down the assertion and the reason step by step. ### Step 1: Understand the Assertion **Assertion:** Work done by a constant force is path independent. - A constant force means that the magnitude and direction of the force do not change. - The work done (W) by a force is defined as the product of the force (F) and the displacement (d) in the direction of the force. Mathematically, this is expressed as: \[ W = F \cdot d \] - For a constant force, the work done depends only on the initial and final positions, not on the path taken between them. ### Step 2: Understand the Reason **Reason:** All constant forces are conservative in nature. - A conservative force is defined as one where the work done is independent of the path taken and depends only on the initial and final positions. - However, not all constant forces are conservative. For example, friction is a constant force but is non-conservative because the work done against friction depends on the path taken. ### Step 3: Analyze the Truth of Each Statement - The assertion is **true** because the work done by a constant force is indeed path independent. - The reason is **false** because it incorrectly states that all constant forces are conservative. Friction is a counterexample to this statement. ### Conclusion Based on the analysis: - The assertion is true. - The reason is false. Thus, the correct answer is that the assertion is true, but the reason is false. ### Final Answer Assertion is true; Reason is false. ---
