Suppose that an experiment determines that the amount of work required for a force field to move a particle from the point ( 1 , 2 ) to the point ( − 5 , 3 ) along the curve c 1 is 1.2 j and the work done by the field in moving the particle along another curve c 2 between the same two points is 1.4 j. what can you say about the field, and why? g

From  the given information we can infer that the field is not conservative.

Explanation:

For a conservative field the work done on an object in moving it from a position given by co-ordinates to another position with co-ordinates  shall be independent of the path we take in between to reach our final position (by definition of a conservative field). But in the given case since the initial and the final position of both the curves coincide but the work done along both the paths is different thus we conclude that the field is not conservative.
