Q. Two horses pull horizontally on ropes attached to a stump. The two forces F1 ⃗⃗⃗⃗ and F2 ⃗⃗⃗⃗ that they apply to the stump are such that the net (resultant) force R⃗ has a magnitude equal to that of F1 ⃗⃗⃗⃗ and makes an angle of 90° with F1 ⃗⃗⃗⃗ . Let F1 = 1300N and R = 1300N also. Find the magnitude of F2 ⃗⃗⃗⃗ and its direction (relative to F1 ⃗⃗⃗⃗ ).
