The correct Answer is:
To solve the problem, we need to determine the total work done in moving a body from point A to point C, given the work done in two segments: from A to B and from B to C. Since the forces involved are conservative, we can simply add the work done in each segment. ### Step-by-Step Solution: 1. **Identify the Work Done in Each Segment**: - Work done from A to B (W_AB) = 20 J - Work done from B to C (W_BC) = 15 J 2. **Use the Property of Conservative Forces**: - For conservative forces, the total work done in moving from one point to another can be calculated by adding the work done in each segment along the path: \[ W_{AC} = W_{AB} + W_{BC} \] 3. **Substitute the Known Values**: - Substitute the values of work done into the equation: \[ W_{AC} = 20 J + 15 J \] 4. **Calculate the Total Work Done**: - Perform the addition: \[ W_{AC} = 35 J \] 5. **Conclusion**: - The total work done in moving the body from A to C is 35 Joules. ### Final Answer: The work done in moving the body from A to C is **35 J**. ---
