Compute the curl of the field and verify that it has the same directionas the axis of rotation.b. Compute the magnitude of the curl of the field. F = ⟨1, -2, -3⟩ x rarrow_forward
- Splitting a vector field Express the vector field F = ⟨xy, 0, 0⟩in the form V + W, where ∇ ⋅ V = 0 and ∇ x W = 0.arrow_forwardVector Calculus For scalar functions u and v, show that B = (Vu) × (Vv) is solenoidal and that A = - vVu) is a vector potential for B, i.e. B = V×Aarrow_forwardRain on a roof Consider the vertical vector field F = ⟨0, 0, -1⟩, correspondingto a constant downward flow. Find the flux in the downward direction acrossthe surface S, which is the plane z = 4 - 2x - y in the first octant.arrow_forward
- Fill in the table and then sketch the vector field. y F(x, y) = -2 -2 -2 2 -2 -2 -2 3- -2- 2. /- 2.arrow_forwardThe figure in this exercise shows a horizontal layer of the vector field of a fluid flow in which the flow is parallel to the xy-plane at every point and is identical in each layer (i.e., is independent of z). State whether you believe that the curl is nonzero at the origin. If you believe that it is nonzero, then state whether it points in the positive or negative z-direction. X O The curl at the origin is zero. O The curl at the origin is nonzero and points in the negative z-direction. O The curl at the origin is nonzero and points in the positive z-direction.arrow_forwardExample Let F = xy? i+ xy j be a vector field in 2-space. Evaluate $. xy? dx + xy? dy where C is the boundary of the triangle with vertices (0,2),(3,2), and (3,5).
