Question
Suppose in a situation like Case 2(a) in the experiment, m1 = 200 g were at the 20-cm position and m2 = 100 g at the 65-cm position. Would there be a problem in experimentally balancing the system with m3 = 50 g ? Explain. If so, how might the problem be resolved?In case 2(a): m1 = 100 g m2 = 200 g m3 = 50 g Suppose in a situation like Case 2(a) in the experiment, m1 = 200 g were at the 20-cm position and m2 = 100 g at the 65-cm position.

In case 2(a): m1 = 100 g m2 = 200 g m3 = 50 g
In case 2(a): m1 = 100 g m2 = 200 g m3 = 50 g
Explanation / Answer
Let y be the position where thel system is balance and x be the position where 50 g is placed.
Takin moment about the zero end
200*20 + (100*65) + 50 x = 350 y
10500+ 50 x = 350 y
Dividing by 50
210 + x = 7 y
7 y = 210 + x
Wecan find x and y such that the above equation is satisfied.
For examle when x = 0, the system will be balanced at 30 cm .
