The work W done by a constant force F as its point of application moves along the vector PQ is given by W=F-PQ Find the work W done in moving a particle from point P(1,3) to Q(-3,5) when the magnitude and direction of the force are given by F = -21+3j. 12. 13) Find the angle 8 between the two vectors u = <0, 2, 2> and v=<3,0,-4>. 13. 14) Determine whether u and v are orthogonal, parallel, or neither for u=<0, 1,6> and v=<1, -2,-1>. 5) Find u xv for u=<-7,1, 12> and v=<2, 2, 3> 14. 15.
