Q.37. The value of m so that elongation in both the identical massless rods are same is (1) m = M 2 (2) m = M 3 (3) m = 0 (4) m = M Share with your friends Share 8 Sanjay Singh answered this Dear student Regards -4 View Full Answer Mohamed Tahirsha answered this let the force in rod 1 and 2 be F1 and F2 and elongation in a rod is given by FL/AY since elongation is same so therefore F1 = F2 now, F2 = Mg and F1 = F2 + mg so if F1 = F2 then mg = 0 implies m=0 -4
