The correct Answer is:
To solve the problem step by step, we will analyze the situation with two springs having different spring constants when equal forces are applied to them. ### Step 1: Understand the Given Information We have two springs with spring constants \( k_1 \) and \( k_2 \), where \( k_1 > k_2 \). When equal forces \( F \) are applied to both springs, we need to determine the elongation in each spring. **Hint:** Remember that the elongation in a spring is related to the force applied and the spring constant. ### Step 2: Apply Hooke's Law According to Hooke's Law, the force exerted by a spring is given by: \[ F = k \cdot x \] where \( F \) is the force applied, \( k \) is the spring constant, and \( x \) is the elongation (displacement) of the spring. For spring 1: \[ F = k_1 \cdot x_1 \] For spring 2: \[ F = k_2 \cdot x_2 \] **Hint:** Since the forces are equal, we can set the two equations equal to each other. ### Step 3: Set the Forces Equal Since \( F \) is the same for both springs: \[ k_1 \cdot x_1 = k_2 \cdot x_2 \] **Hint:** Rearranging this equation will help us find the relationship between \( x_1 \) and \( x_2 \). ### Step 4: Solve for Elongations Rearranging the equation gives us: \[ x_1 = \frac{k_2}{k_1} \cdot x_2 \] Since \( k_1 > k_2 \), we can conclude that: \[ \frac{k_2}{k_1} < 1 \] This means: \[ x_1 < x_2 \] **Hint:** This indicates that the elongation in the spring with the larger spring constant (spring 1) is less than that in the spring with the smaller spring constant (spring 2). ### Step 5: Calculate Work Done on Each Spring The work done on a spring is given by: \[ W = F \cdot x \] For spring 1: \[ W_1 = F \cdot x_1 \] For spring 2: \[ W_2 = F \cdot x_2 \] **Hint:** Since \( x_1 < x_2 \), the work done on spring 1 will be less than the work done on spring 2. ### Step 6: Compare Work Done Since \( x_1 < x_2 \) and the force \( F \) is the same for both springs: \[ W_1 < W_2 \] Thus, we conclude: \[ W_1 < W_2 \] **Final Conclusion:** More work is done on spring 2 (the one with the smaller spring constant). ### Summary of the Answer The work done on spring 2 (with spring constant \( k_2 \)) is greater than the work done on spring 1 (with spring constant \( k_1 \)). **Final Answer:** More work is done on spring 2.
