- A light elastic string \(A B\) has natural length \(11 a\) and modulus of elasticity \(6 m g\)
A particle of mass \(4 m\) is attached to the point \(C\) on the string where \(A C = 8 a\) and a particle of mass \(2 m\) is attached to the end \(B\)

The end \(A\) of the string is attached to a fixed point and the string hangs vertically below \(A\) with the particle of mass \(4 m\) in equilibrium at the point \(P\) and the particle of mass \(2 m\) in equilibrium at the point \(Q\), as shown in Figure 1.
