If the system of blocks shown in the figure is released from rest, the ratio of the tensions \(\mathrm{T}_1\) and \(\mathrm{T}_2\) is
(Neglect the mass of the string shown in the figure)
- A \(1: 1\)
- B \(1: 2\)
- C \(1: 3\)
- D \(3: 4\)
Answer & Solution
Correct Answer
(A) \(1: 1\)
Step-by-step Solution
Detailed explanation
For block 2M: \( (2M)g - T_1 = (2M)a \) For block M: \( T_1 - T_2 = Ma \) If the system is released from rest and remains at rest (equilibrium), then \( a = 0 \). \( (2M)g - T_1 = 0 \Rightarrow T_1 = (2M)g \) \( T_1 - T_2 = 0 \Rightarrow T_1 = T_2 \) Therefore,…
