Two block of masses m and M are connected by means of a metal wire passing over a frictionless fixed pulley. The area of cross-section of the wire is 6.5×10−9m2 and its breaking stress is 2×109Nm−2. If m=1kgif the maximum value of M is K x 1.86 kg for which the wire will not break. Find the value of K.g=10m/s2
