As can be seen in the figure, the first rope pulls a hook attached to the ceiling with a force of 8kN at an angle of 75 degrees, and the second rope with a force of 6 kN at an angle of 30 degrees. So what is the total force acting on the hook? (Cos105 = -0.25 = 1/4) A) 8.71 N B) 9.61 N 12 - F2 = 6 KN C) 6.61 N Fl =8 KN D) 10 N E) 7.81 N
