Question:

A force in the xy plane is given by F = (F₀/r)(yi - xj), where F₀ is a constant and r = √x² + y² .

(a) Show that the magnitude of this force is F₀ and that its direction is perpendicular to r = xi + yj.

(b) Find the work done by this force on a particle that moves in a circle of radius 5 m centered at the origin. Is this force conservative?
