The horizontal rod OA rotates about a vertical shaft according to the relation θ = 10t, where θ and t are expressed in rad/s and seconds, respectively. A 0.5-lb collar B is held by a cord with a breaking strength of 4 lb. Neglecting friction, determine, immediately after the cord breaks,

(a) The relative acceleration of the collar with respect to the rod,

(b) The magnitude of the horizontal force exerted on the collar by the rod.
