Question 2 ( a ) The force of an object is given by: vec ( F ) = ( x 2 y z ) i
Question
a The force of an object is given by:
vec
Evidence that the vector vec is conservative. Then, determine the work done by the following field, if the force is moving along any smooth curve joining and
marks
b Calculate the work done by the following vector which travels from to then from to followed by to before going back to from All the travel paths are straight lines. Solve the problem using Green's theorem.
