Test Academy | Two blocks of masses m₁ and m₂ are joined by a wire of Young’s modulus Y via a massless pulley. The area of cross-section of the wire is S and its length is L. When the system is released, increase in length of the wire is m₁m₂gL/YS(m₁+m₂), 2m₁m₂gL/YS(m₁+m₂), (m₁-m₂)gL/YS(m₁+m₂), 4m₁m₂gL/YS(m₁+m₂)
