A) \[{{W}_{1}}>{{W}_{2}}>{{W}_{3}}\]
B) \[{{W}_{1}}<{{W}_{2}}<{{W}_{3}}\]
C) \[{{W}_{1}}={{W}_{2}}={{W}_{3}}\]
D) \[{{W}_{1}}={{W}_{2}}<{{W}_{3}}\]
Correct Answer: B
Solution :
[b] Reading of the weighing machine \[=2T+\] weight of the machine. As weight of the machine is constant. \[T=\frac{2{{m}_{1}}{{m}_{2}}}{{{m}_{1}}+{{m}_{2}}}\] So reading is maximum for the case \[{{m}_{1}}{{m}_{2}}\] is maximum as \[{{m}_{1}}{{m}_{2}}\] in all cases is same.You need to login to perform this action.
