Alright, I did a lab today. Where I had to suspend a mass of 230g from a string attached to a Newton-meter between two clamp and stands.(adsbygoogle = window.adsbygoogle || []).push({});

I also recorded values of angles.

My question is for the calculations it says

The equation F and θ is

F= mg/sinθ + k

where m is the mass of the load, k is a constant and g is the acceleration of free fall.

You may take the value of g to be 9.81 m/s^{2}

Determine the value for m and k.

and Determine the percentage uncertainty in the value of θ.

Okay I am confused, why would I need to determinem? Ismnot 230g?

and i'm not sure how to calculate percentage uncertainty..

HELP WOULD BE MUCH APPRECIATED.
