Figure 43 the Figure Shows Two Objects of Masses M₁

question 1

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, the two masses are the same (m₁ = m₂ = 10 kg) ; the incline angles are è₁ = 30° and è₂ = 50°. What are the magnitude and direction of the acceleration of the system, and the tension in the string, if both inclined surfaces are frictionless?

• A)1.3 m/s², 62 N
• B)2.6 m/s², 75 N
• C)6.2 m/s², 13 N
• D)6.2 m/s², 111 N
