Yeah I realized the problem. The reason why I still attempted was because I was intrigued why it was so difficult. Anyway, long story short, we were not told until today that a mistake had been made, and we were meant to assume we already knew the tension force of 2N for both strings. From that...
I've tried various ways to produce the value of gravity (guess and check method - not ideal but it may help me realize), therefore I have achieved numerous results. The closest I got was a magnitude of 7.
1. We had to set up an experiment that looked like the attached diagram. By adding different masses (independent variable) we would measure angle theta (dependent variable). Our task was to draw an appropriate graph and from the gradient, see what our gravity value came to.
So far i...
