Answer:
200N
Explanation:
Distance from fulcrum by you = 0.5m
Distance from fulcrum by cousin = 1.5m
Your weight = 600N
Unknown:
Weight of my cousin = ?
Solution:
From the principle of moment, when an object is balanced, the sum of the clockwise moment is equal to the sum of the anti-clockwise moment.
So;
Your weight x distance from fulcrum by you = Weight of cousin x her distance from the fulcrum
600 x 0.5 = weight of cousin x 1.5m
Weight of cousin = 200N
