3. The work Wdune by = xf + 3xryj - (x + z)k to move a particle from point 1 to point 2 is defined by W12 = S} •dř where i, and i, are corresponding position %3D vectors. If f is perpendicular to the direction of motion, W =0. If = x²zt – 2y°z²9 + xy²zk, then the divergence of F at (1,0,0) = -3. 4. %3D 5. Given: R = 3x?1 + 2zf – xk; thus, rot Ř = -i+ 2f – k.
