was the force labeled in the diagram (from friction or whatever was in the question) just the frictional force or the resultant (centripetal force) basically what im asking is, is that force in the diagram F= mv^2 / r or is the centripetal force the horizontal to that?
I said that it was to do with the time constant (RC) needing to be low but I'm not sure if that is correct?
I'm not sure myself, I didn't actually get to answer it because it was confusing. All I remember was the question stating it needs to detect minute changes in the distance. Probably because silicon is used in sensitive circuits?

they gave you the mass of the guy in the question, your method ignores mass, surely if they wanted you to eliminate mass, they wouldnt have given it to you in the first place.....

No, they gave you the mass so that you don't get confused and so that you can follow the straight forward method. Eliminating the mass is acceptable as circular motion never depends on the mass anyway.
