A particle moves from point A = (0, 0, 0) to point B = (2π, 0, 2π), under the action of the force F = xi + yj − zk .
a. Calculate the work done by the force F on the particle if it moves along the conic-helical curve
r(t) = (t cost )i + (t sint )j + tk with 0 ≤ t ≤ 2π.
b. Find a parametric vector equation for the straight line connecting A to B, and calculate the work done by the force F on the particle as it moves along this straight line.
c. Is the force F conservative or not?
