If the quantities measured in order to verify eq.(3) were obtained with values as in problem 1, estimate the fractional error (%) on the left side and on the right side of the equation. use the uncertainties originating from the precision of the measuring equipment: the pulling mass is measured by slotted weights with 10 gram increment (uncertainty +/- 5 gram), the rotating mass is measured by a beam balance with uncertainty 0.1 gram, the rotating radius is measured by a meter stick with 1mm divisions (uncertainty +/- 1 mm), and the period of rotation is determined by measuring the time for 10 revolutions, with 0.5 s uncertainty of that time due to the human reaction at operating of stop watch.
