3. Find the work done by the force field F(x,y,z) = zi + xzj + (xy +z)k along a straight line segment from (1, 0, -2) to (4, 6, 2).© BrainMass Inc. brainmass.com October 16, 2018, 9:44 pm ad1c9bdddf
The solution shows how to calculate the work done by force field along the line segment by line integral.

4. Find the work done by the force field F(x, y, z) = -zi + yj + xk in moving a particle from the point (3, 0, 0) to the point (0, pi/2, 3) along:
(a) a straight line
(b) the helix x = 3cos(t), y = t, z = 3sin(t).
