Question

when k = 2.10. (Take ? = 22.0

F FA A baby elephant is stuck in a mud hole. To help pull it out, game keepers use a rope to apply a force F rightarrow A, as part a of the drawing shows. By itself, however, force F rightarrow A is insufficient. Therefore, two additional forces F rightarrow B and F rightarrow C are applied, as in part b of the drawing. Each of these additional forces has the same magnitude F. The magnitude of the resultant force acting on the elephant in part b of the drawing is k times larger than that in part a. Find the ratio

Explanation / Answer

As the forces FB and FC are equal the horizontal component of force is given as FB = FC = F
