Two masses m1 and m2 which are connected with a light string, are placed over a frictionless pulley. This set up is placed over a weighing machine, as shown. Three combination of masses m1 and m2 are used, in first case m1=6kg and m2=2kg, in second case m1=5kg and m2=3kg and in third case m1=4kg and m2=4kg. Masses are held stationary initially and then released. If the readings of the weighing machine after the release in three cases areW1,W2 and W3 respectively then:

Question

Two masses m1 and m2 which are connected with a light string, are placed over a frictionless pulley. This set up is placed over a weighing machine, as shown. Three combination of masses m1 and m2 are used, in first case m1=6kg and m2=2kg, in second case  m1=5kg and m2=3kg and in third case m1=4kg and m2=4kg. Masses are held stationary initially and then released. If the readings of the weighing machine after the release in three cases areW1,W2 and W3 respectively then:

Filo · Accepted Answer

[b] Reading of the weighing machine =2T+ weight of the machine. As weight of the machine is constant. T=2m1m2m1+m2 So reading is maximum for the case m1m2 is maximum as m1m2 in all cases is same.
