Same spring is attached with 2 ~kg , 3 ~kg and 1 ~kg blocks in three different cases as shown in figure. If x₁, x₂, x₃ be the extensions in the spring in the three cases, then

Step-by-step solution

If T₁, T₂, T₃ are the tensions in the strings in the three cases, we have aligned & T₁= 2 m₁ m₂ g m₁+m₂ = 2 2 2 g (2+2) =2 g & T₂= 2 3 2 g (3+2) =2.4 g & T₃= 2 1 2 g (1+2) =1.33 g & As x T and T₂>T₁>T₃ & x₂>x₁>x₃ aligned
