Figure shows a 12 kg block that is on the verge of sliding up the ramp because of a tension force from the cord that is parallel to the ramp. The ramp's angle is 8 = 30° and the coefficient of static friction is 0.80. What is the magnitude (N) of the tension force? a) 98.6 b) 172 c) 140 d) 102 e) 333 T
