3) a metre-stick is found to balance at the 49.7cm mark when placed on a fulcrum, when a 50g mass is attached at the 10cm mark the fulcrum must be moved to the 39.2 cm mark for balance. what is the mass of the meter stick?
- just plain stuck on this, tried about 3 different ways of attempting the question, but couldn't find one that suited! anyone got any ideas on how to start it?? again, any help appreciated!
