A baby elephant is stuck in a mud hole. To help pull it out,game keepers use a rope to apply force FA, as part(a) of the drawing shows. By itself, however, forceFA is insufficient. Therefore, two additionalforces FB and FC are applied, as in part (b)of the drawing. Each of these additional forces has the samemagnitude F and is oriented at θ = 20.00away from FA. The magnitude of the resultant forceacting on the elephant in part (b) of the drawing is twice that part a. Find the ratio F/FA.
