Morila Firelo 80744232 Chapter Elgh Conceptual Exercise 8.1 Conceptual Exercise 8.1 Part A What is the work done by this force on path 1? Express your answer using one significant figure. The work done by a oonservative force is indicated in the urses fiqure for a variety of different paths connecting the points A and B W 18 e Tools Incorrect, Try Again; 5 attempts remaining Part B What is the work done by this force on path 27 Express your answer using one significant figure W-61 w 18 Type here to search DOLL 3 4 5 6

Explanation / Answer

For a conservative force, the work done from point A to point B is independent of path. Given that the work done along middle path is 15 J.

The work done along the right path =18 J+Work done along path 1. This should be equal to 15 J.

Hence the work done along path 1 = 15 J - 18 J = - 3 J

Part B

Similarly, the work done along the path 2 = 15 - (-6 - 5) J = 15 + 6 + 5 J = 26 J
