Two blocks M2-2M₁ = 4 kg are attached to the ceiling of an elevator cabinet and are connected by massless non- stretchable strings as shown in the figure. The cabinet is accelerating downward at a constant rate of 4.7 m/s². The magnitude of the tension 7, (in N) in the upper string is: M 41.2 31.8 zero 50.6 22.4 09000 T₁₂ M₂
