Two children weighing 17 and 20 kilograms are sitting on opposite sides of a seesaw, both 2 meters from the axis of rotation. wh
ere on the seesaw should a 10-kilogram child sit in order to achieve equilibrium?
1 answer:
In order to achieve an equilibrium some of momentum should be zero about the axis of rotation.
Suppose, the 10-kilogram child is placed X meters away from the axis of rotation.
Now, according to the question
17x2+10X-20x2=0
X=0.6m
Child should sit 0.6m away from the axis of rotation towards 17 Kg child.
