3 The fixed points E and F are on the same horizontal level with \(\mathrm { EF } = 1.6 \mathrm {~m}\). A light string has natural length 0.7 m and modulus of elasticity 29.4 N . One end of the string is attached to E and the other end is attached to a particle of mass \(M \mathrm {~kg}\). A second string, identical to the first, has one end attached to F and the other end attached to the particle. The system is in equilibrium in a vertical plane with each string stretched to a length of 1 m , as shown in Fig. 3.
