A balanced lever has two weights on it, the first with mass 1 kg and the second with mass 9 kg. If the first weight is 3 m from the fulcrum, how far is the second weight from the fulcrum?

0.33 m
Explanation:
The torque or moment of each of the weights about the fulcrum is equal because the lever is balanced.
Torque= Fd
F= mg
F - Force (mass x gravitational
acceleration)
(1kg)(3m)/9 kg
