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?
