Question

In the figure, M2 has more mass than M1 and M1 has more mass than M3. The questions refer to the magnitudes of tensions and weights. There is friction between the horizontal plane and M2 (?k ? 0). M2 is observed to travel at a constant speed. Assume that the pulleys are frictionless and have negligible mass. Select the appropriate statements to complete the following sentences. M1 accelerates downwards. T3 is ... T2. The magnitude of the net force on M2 is T2 - T3. T1 is ... T2. T4 is ... M3g T1 is ... M1g. either true or false or less than or greater than or equal to

Explanation / Answer

M2>M1>M3 T1=T2 and T3= T4 (since tension in the same rope is same throughout) Since M2 is travelling with constant speed there is no acceleration so net force acting on M2 is 0 => T2=T3+kM2g thus T2>T3
