Question 24 NECO_MODEL_QUESTIONS_VOL1 • 2023 • PHYSICS • objective

A system consists of two masses, \(m_1 = 4\ \text{kg}\) and \(m_2 = 6\ \text{kg}\), connected by a light inextensible string that passes over a uniform solid cylinder of mass \(M = 2\ \text{kg}\) and radius \(R = 0.20\ \text{m}\). The string is wound around the cylinder so that when the masses move the cylinder rotates without slipping. Assuming the pulleys are frictionless, find (a) the magnitude of the common acceleration of the masses, and (b) the tension in the string on each side of the cylinder.

Answer Options

A. a = 1.78 m\/s²; T₁ = 48.1 N, T₂ = 46.3 N
B. a = 2.05 m\/s²; T₁ = 44.0 N, T₂ = 50.2 N
Correct Answer C. a = 1.78 m/s²; T₁ = 46.3 N, T₂ = 48.1 N
D. a = 1.20 m\/s²; T₁ = 42.5 N, T₂ = 45.0 N
Correct Answer
C
Correct Option:
a = 1.78 m/s²; T₁ = 46.3 N, T₂ = 48.1 N
