In my data.... P is 100g; Q is 100g; a is 18.4 cm; and b is 17.8 cm.... we are given the formula: Pa=Wc+Qb I'm not sure if W is 200g because I don't remember if we put a 200g weight....but I assume it is 200g it is to balance it to P and Q my question is: what is Pa, Qb and c? I'm gonna draw the diagram of our experiment...(wait)
