Multiple Choice

Figure 4.3 The figure shows two objects of masses m₁ and m₂, placed on two inclined surfaces of different angles è₁ and è₂. The connection between masses is a taut, massless string running over a massless and frictionless pulley.
-In Fig. 4.3, masses are m₁= 10 kg and m₂ = 15 kg; incline angle is è₁ = 30°. What is the value of è₂ if the system is NOT moving?

A) 71°
B) 49°
C) 41°
D) 20°
