Homework Statement
A metre stick is found to balance at the 49.5cm mark when placed on a fulcrum. When a 47.7 gram mass is attached at the 1.5cm mark, the fulcrum must be moved to the 38.6cm mark for balance. What is the mass (in grams) of the metre stick.
Homework Equations
Torque = Force x Distance
F = ma (?)
The Attempt at a Solution
Ok, well, I thought the torque equation would be good for this, but then again, what is the point of finding torque, when I can't use it to find the mass? Or can I?
I was thinking about finding Force (0.0477 x 9.8), but that just leaves me with Force.
Am I going completely wrong about this question or am I on the right track? Any help would be greatly appreciated.
