A stationary plate in the plane can rotate around |
A stationary plate in the plane can rotate around the origin. If a force of (−2,2) N is applied at (5,0) m and a force (−4,5) N is applied at (−2,1) m, what is the signed magnitude of the force that can be applied at (−2,0) in the direction (−4,−5) to keep the plate from rotating?
