A wire of 10^(-2) kgm^(-1) passes over a frictionless light pulley fixed on the top of a frictionless inclined plane which makes an angle of 30° with the horizontal. Masses m and M are tied at two ends of wire such that m rests, on the plane and M hungs free!) vertically downwards. The entire system is in equilibrium arid a transverse .jvave propagates along the wire with a velocity of 100 ms^(-1). Then |
