#20) F(x) = ((r^2) - 2r) x where x = <x,y> and r = | x | 
Note: I’m not very comfortable with vectors, so when it requires an x component and a y component, in reference to this question, I’m not quite sure what it means, but I’m going to answer the problem from here assuming that this is correct, but I don’t know for sure.

VectorPlot[{ r^2 - 2*r,r = Abs[x]},{x,-5,5},{r,-5,5}]

# 26)

VectorPlot[{x/(x^2+y^2)^(1/2), y/(x^2+y^2)^(1/2)}, {x, -3, 3}, {y, -3,3}]

# 36)

VectorPlot[{1,x},{x,-3,3},{y,-3,3}]
